@AnnemarieBridy It's best to get a TV with a Google TV or Android TV interface as it has a basic mode where the internet features can be turned off on setup. https://arstechnica.com/gadgets/2021/02/the-best-feature-of-google-tv-you-can-turn-it-off-for-a-dumb-tv-mode/
Sony and some Hisense and TCL TVs have it.
