I have my LGs connected, but logged out.
It's a hassle in that it requires to log in and then back out for mandatory updates of some apps (others will update without a logout, for some reason), but at least it removes the need to agree to a whole bunch of their garbage and add it to an identifying account.
I would keep it offline and use a set-top box, but I have family members that aren't tech savvy and won't want more hassle than pressing the "Netlfix" button on the remote.
I'll say that even they are increasingly annoyed at the constant cookie prompts during live TV watching. Honestly broadcast TV is an absolute hellscape these days.
