It looks like the checking and savings accounts are brokerage accounts, so if you put money into it then you are buying securities.

I just learned that this is how Betterment's "Smart Saver" account is as well.

No. Robinhood offers Checking & Savings through a brokerage account and it offers the Robinhood debit card in partnership with Sutton Bank.
