Just get a non smart tv and an android box to hook up to it
Better yet, get a Roku box instead of android box to keep from being so wed to Google. And it doesn't matter if the tv is smart or not (it might be hard to find a high resolution tv without the smarts).
My TV is a smart TV, but I never see its startup screen. That's because I start my TV viewing by pressing the Home button on my Roku remote, never having to press the power button for the TV. When the TV picks up a signal from that HDMI port, it automatically turns on and goes straight to that port (bypassing the tv's "home" screen). So the first few seconds of my TV viewing experience is black screen then straight to Roku channel selection screen.
Then there's the fact that the various apps on the Roku device upgrade easier than the related apps on a TV. For example, I pay for the Paramount+ (CBS) during football season to watch SEC games because I live in an area where even HD antennae signals are bad. During football season I catch up on old NCIS and Blue Bloods episodes, then discontinue my membership after college football season ends (unless my alma matter is doing unusually good in basketball season LOL). When the football season begins again in the fall and I launch the Paramount+ app for the first time in over half a year. At that point the app updates. Over the years, the few times it was unable to update (because my Roku device was too old) I replaced my Roku device without having to buy a TV (because it doesn't matter that the TV is old because the TV isn't what's running the app).
