Pay-as-you-go phones work. A $15 (sometimes free) basic cellphone with a few minutes are all you need. Once the account is set up, the phone isn’t needed. I’ve made quite a few Google throw-away accounts this way. Just never lose your password and don’t turn on 2FA.

As far as Google tracking goes - you can firewall off all the Google servers if you dislike them, or use a router that connects through a VPN if you need that level of privacy.
