Speaking from experience here, they don't ban your entire Google account, they block access to Antigravity (and only that, other Google AI services are still available). Pi very briefly supported logging into Antigravity a few months ago, I did so and made a couple of toy queries and then didn't use it again, and my Antigravity access was suspended until a few weeks ago.
The process to get un-suspended was completely byzantine and Google's own support desk wasn't able to do anything. I just kept trying newer versions of Antigravity until it eventually grew the ability to explain what was going on and then let me request access back.
