Do we know if Google Voice also uses T-Mobile? If not, might be worthwhile to switch SMS 2FA to the Voice number if a service allows voip numbers.

Google Voice isn't a wireless carrier. VoIP only.

This is part of my question. How does Google provision VoIP numbers? When someone calls / texts a VoIP number from a normal number, that call / SMS travels over normal wireless infrastructure. So VoIP numbers are still connected to the same infra, right?

As I understand it, yes, but not through a wireless carrier. They'd tie into the infrastructure somewhere else. They'd be more of a peer with Tmobile then a customer.
