Regarding having to provide a phone number to sign up for a Google account, I've always had luck with connecting behind cellular data while signing up using the Play Store: this presents a 'Skip' button when Play Store asks me for a number, and still avoids me having to provide my residential IP address (I rarely connect to the internet with cellular data without using a VPN, and the IP address I receive from my carrier also changes when I reboot the phone). (I have written about my experience here).
