Google has already been crippling the audio CAPTCHA access for many years. If your trust score is low enough, the visual challenge is ridiculously slow and noisy, and pressing the audio challenge button will just give you an error saying "To protect our users, we can't process your request right now", accessibility be damned. Where are the lawsuits? I want to believe there are still forces that would create hell to pay for doing something so evil, but I'm not seeing any.

They'll keep it, but require TPM in each ear.

Haven't you heard? Accessibility is woke, and the institutions that are supposed to protect it are being dismantled. I wouldn't be counting on those lawsuits going anywhere personally.
