I never connect any “smart” device to wifi. If it doesn’t work without connectivity, I don’t want it. I use my TVs as display devices. They have HDMI-in and that’s it.
That's fine! With technologies like Amazon Sidewalk and cheap and cheerful 4g/5g radios nobody NEEDS to ask your permission to connect any more. You COULD use an older device but you don't want to be left behind, do you? And your peers will think you're poor or possibly a C.H.U.D. if you don't just accept your digital yoke.
Frustratingly I do want some of the functionality that comes with connecting my TV to the network - specifically the ability to control things like turning it on and choosing which input its set to via an API it exposes. That's manageable by putting it on a VLAN which isn't allowed access to the outside world, but its also really annoying to me that I have to do that.
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.
I have a smart TV that's never spoken to the internet after exiting the factory, but it's a pretty tenuous state of affairs. I have this fear that someone staying over is going to see the "Services unavailable, press [menu] to troubleshoot" toast that shows up overtop the HDMI feed for a few seconds and think they're helping me by connecting it. 4-5 years worth of firmware updates all at once... half a decade of watch data somehow extracated from the HDMI feed and stored for precisely this moment... ads everywhere. Even if it doesn't happen instantly, I can only assume there's some flag deep in the OS called makeEverythingWorse just waiting to be flipped on the femtosecond The Beast catches a whiff of a slightly-higher patch number; now content in it's doomed state after having fufilled it's one true purpose of telling someone at samsung my favourite show is HDMI2.
I have had to back my mother down from that precipice on her own TV so I know it's worth worrying about. The siren call of an entirely empty TV homescreen beckoning us with a struck-out radio tower icon. "We have Disney+ and CraveTV too... press [menu]... pay no attention to the sticky note your son put on the coffee table"
