On my TCL TV, you have to connect it to read the Google policies you are agreeing to. If you don't, you agree to policies unread.
Thankfully, the blast radius of this is nothing without connectivity.
If it has an Ethernet port I would use that then unplug it. It still gets to phone home once but you don't have to worry about it maliciously saving your Wi-Fi password for later
But it lets you continue without reading them? There's a lot of questionable terms of service rules but this one has to be unenforcable.
If I don't connect to the internet ever, my agreement to Google policies is probably a moot point.

Sounds like a great reason to return a TV. It isn't like you must have a TCL TV.
