Assuming the story isn't simply made up, I'd rest easier knowing whatever caused the problem (both the initial mass banning and Google's unwillingness to help) has been fixed.
We're limited on what we're able to share in public forums related to specific customer situations.
If you're not already doing the following we recommend the following steps to protect your G Suite account - have more than one super admin - ensure an up-to-date recovery email is in the account profile - ensure an up-to-date recovery phone is in the account profile - ensure account profile is properly updated - use two factor authentication for all users (ideally user security keys) - at a minimum, ensure that your G Suite administrator users are using two factor authentication

I realize you can't comment on specific incidents, but a simple statement from Google saying "no, we definitely won't ban entire organizations including connected personal accounts because of one user's actions" would go a long way to put people at ease here.
They won't make a blanket statement like you want because there are bad actors out there that they have to respond to.
Anyways, there's 24x7 phone support and ways to get support even if you're completely locked out. What more do you want?
Umm the 24x7 phone support number is not listed on the web page.
To get the phone number, you need to log in.
How do you log in, if you're locked out?
