Good privacy friendly TV setups

I was looking to buy a TV for my living room, but many people say that smart TVs are a privacy nightmare. I thought maybe I could buy a smart TV, disconnect it from the internet and plug in a raspberry pi or something. But I really don't want to control it with a mouse and keyboard. 😵

So do any of you know of any good privacy friendly TV setups? Or know which brands are the least privacy invasive? Thanks ☺️
