I have a cheap samsung from 5 years ago that pops up a dialog when it boots. I've never read it or agreed to it. It goes away after about 5 seconds. After that I stream using HDMI and all is well. It's also never been connected to a network.

Can't say what other TVs do, but this one works fine without TOS etc. If there is some feature or other that doesn't work due to this, I can say I've never missed it.
