I recently bought a TV and faced exactly this. Basically, I use my TV for two things: a RPi with Kodi (LibreELEC) from which I do all my 'watching' and a Nintendo Switch. Both of those devices are connected via wifi. There is no reason whatsoever to have my TV do anything else than 'be a screen' and connect to my soundbar - yet it was nearly impossible to get a dumb tv anywhere where I live (Belgium) without paying ridiculous extra costs.
Ended up buying a Samsung QLed (marketing bling) TV that I never connected to my network. Switching between input devices requires 6 buttons presses (!) because it keeps nagging to connect the TV to the internet.
Also on some Samsung tv: it needs to connect to download the Terms and Conditions, then it will prompt you to accept them and then it will work/remember last used input. The download happent overnight on very good net access, I guess because their servers are very busy.
