You can't create a Google account without a phone number (at least last I tried), however once you enable a 2FA method other then SMS you can then delete the phone number. To their credit the phone numbers I gave to Google when setting up my accounts have never shown up in any of the usual law enforcement or skip trace databases so I'm less apprehensive about opening new accounts with them.
T-Mobile sells me out once a year - I don't even give them my real name, they must get it from my credit card or something. This year I used a fake name "authorized user" card, still waiting to see if that keeps my latest number out of the databases or not, around nine months to go.
