even if there were some kind of massive spam event, Google isn't going to block emails from its own IP blocks or domains from reaching Gmail or Gsuite customers
When I worked there it absolutely did do this. Yes it seemed stupid to me at first too, but all it takes to end up like that is to decide not to give yourself unfair special exceptions to your own policies, which is how things should be!
frankly, I would be shocked if any of the various DNS blocklists that people use for determining who's a dirty spammer would actually put a Google IP block on there
Be shocked. It did happen when a particularly clever spammer got through the controls. There are no bits of logic in most email servers that say "if IP is owned by Google, ignore". Spam filters are all relative. If senders send a lot more good mail than bad, they're good. If they send a lot more bad mail than good, they're bad. Google IPs are rarely blocked because they send a lot of good mail and invest a huge amount of money and time in keeping it that way.
