It's not particularly onerous to create burner google accounts for what's needed. I have one per GOS phone. A couple tips if you go that route is use public WiFi, or create it through the YouTube website. That should prevent you needing a phone number. Just make sure to enable 2FA with an authenticator so you don't get prompted for a phone number in future.
With the ability to run profiles, you could toss your Google account in a separate profile only for your banking.
