Btw I have had this issue before I delete multiple accounts tbh. "Only doing it if you have enabled 2FA is a straight up lie". If you enable TOTP you will still get the dialouge but at least you can proceed instead of being given absolutely no options of "veryfying yourself".
Though it would be best if you just delete the entire account. The only google service I use is mostly youtube preferably trough freetube or another client
I mean easy to fork but to install might be a challenge and may also put you at risk with the legal system.
