Dumb TVs would cost more because availability of smart functionality earns manufacturer subsidizes from various streaming services while the cost of extra hardware is really low (you can get streaming sticks for under $50). Just don't connect to network and enjoy getting a nicer TV for your money. Also on Android-based TVs you can disable any unwanted apps through ADB or install a privacy-enhancing firewall, so that's one middle option.
