LG C1 OLED here, and my setup is rather simple and has been going just fine with zero issues for over a year now (with no update requests or anything like that). I set it up normally at first, but software updates and such were annoying. LG TV has been connected to my router using wifi, so I simply clicked the "block internet connection for this device" in my router settings, and that was the end of my issues. As for how I deal with outdated apps and such on the smart tv, I have never used them in the first place. AppleTV has been hooked to the LG TV the entire time, and all apps are used from the AppleTV side. Haven't had a single "update your tv software" dialogue even once since then.
