terrorwave I doubt that there are (legal) alternatives for watching American football games, besides actual cable TV.
You can set up a burner google account and pay in gift cards if you want to but in order to access YouTube TV from your phone, you will need the app which requires location permissions to function anyhow. For this case, I have a GrapheneOS profile with YouTube TV and proton VPN (I normally only use/recommend mullvad, but proton isn't blocked by YouTube TV and mullvad is). The profile is not allowed to run in the background so the only time location is on is when I absolutely need to watch on the go.
