The fundamental question then is: was this intentional on behalf of the foreign agent to provide a "thing of value" to a US political campaign, and/or did a political candidate or campaign solicit this?
I suppose you could argue that ads which advocate for a political candidate could count as a "thing of value" for that candidate, but even in that case, there _is_ no foreign national to punish here; the entity that funded the effort is a foreign government, not an individual person.
Likewise, foreign national is a legal term that includes foreign principals, which includes governments, see 22 U.S.C. § 611.
"Under federal law and Federal Election Commission regulations, both foreign nationals and foreign governments are prohibited from making contributions or spending money to influence a federal, state or local election in the United States. The ban includes independent expenditures made in connection with an election.
Those banned from such spending include foreign citizens, foreign governments, foreign political parties, foreign corporations, foreign associations and foreign partnerships, according to the FEC."
How is that enforced? A US court can't exactly send the Russian government or the Communist Party of China to prison for breaking the law here, can it?
"The Federal Election Campaign Act (FECA) prohibits any foreign national from contributing, donating or spending funds in connection with any federal, state, or local election in the United States, either directly or indirectly. It is also unlawful to help foreign nationals violate that ban or to solicit, receive or accept contributions or donations from them. Persons who knowingly and willfully engage in these activities may be subject to fines and/or imprisonment." [0]
The definition of "foreign national" is quite broad.
How this works with regards to PAC contributions is unclear to me.

Who are these "persons"?
It can't logically be the foreign nationals who are attempting to help a campaign. They're not under the jurisdiction of US federal law.
It also can't logically be the candidates. Otherwise, the obvious tactic would be to provide overt, unrequested aid to the opposition candidate(s) and send them all to jail.
I'm not sure it can be Facebook or other Internet sides. It is true that Facebook is a US company, but the content on their sites is protected under the DMCA safe harbor exemption. And then the law wouldn't handle the case of sites not under US ownership.
FECA dates back to the 70s, and it doesn't seem to do a good job of handling the globalization of the Internet. If someone from overseas looked at the facts themselves and, without talking to a candidate, just plastered Google and Facebook and YouTube and Twitter with endorsement of one candidate and criticism of another, is it reasonable to try to stop them?
Criminal violations of US laws whose prohibition is not expressly territorially restricted that occur outside of the US are successfully prosecuted in US courts with some frequency. Bringing people before the court for prosecution may be challenging where extradition isn't an option, but outright kidnapping from a foreign country or even full-scale military military invasion to do so have occurred.
I'm a foreign individual who went around making comments on the US election... what's the difference between me doing it privately and a company doing it?
They do have jurisdiction over the candidate and campaign you endorse, though. If you contacted your candidate and offered them money or services in the hope that they could use your help to get elected, and they accepted your offer they would be guilty. You wouldn't be.
Unfortunately, it seems like a fairly impotent law if all you have to do as a foreign national with an interest in the election is to support a candidate without their endorsement.
You might want to check with Humberto Álvarez-Machaín (acquitted, sure, but not because the law didn't apply to him) or Manuel Noriega about that.
I guess not on US TV or US billboards since they're under the control of the US. But if I buy ads on the internet that just happen to be seen by US citizens there's nothing the US can do about it, right?
For example, let's assume a foreign government decided to purchase ads either backing or attacking a US political candidate, and they were completely overt about it. (No hiding behind shell companies or transferring funds anonymously; completely out in the open.) Are there any laws or systems currently in place which would stop them from doing that?
