Your comment is not accurate in the sense that it is currently not possible to enable 2FA on an account without it without a phone with either SMS verification or with a Google app prompt. If you have set it up in the past, before this, it will look different to you. If you set it up right now, you can remove the phone number later but somewhere in the bowels of Google the number will probably still remain to tie it to your dossier.
