"If you use GrapheneOS, you can enable or disable internet access for each app."

This can also be done on Android with certain apps such as Netguard and PCAPDroid

(Using either a blacklist or whitelist approach)

Disabling internet access is not necessarily a hard requirement to stop this type of spying

Controlling what DNS data apps can access, if any, will usually suffice

Motorola needs to hurry up and release their GrapheneOS devices, I need a new phone soon(TM) (next year or two) and I refuse to give google money to buy hardware to avoid Google.

+1, I'm pretty happy with my used Pixel, but I feel that buying used is still supporting the manufacturer somewhat. People are more likely to buy another if they got a good price for their old one. And you're driving up used prices which may contribute to others buying new. I don't have a rigorous understanding of this though, would be interesting to see an economist's take.

Not sure what information you're expecting the app in question to surface if you disable internet access for it.

An error? It's useful to know if/when an app wants to access the Internet. So if an app says it's local only you can disable network permissions. Trust but verify.
