If your TV is getting internet via your wifi router, there's a thing called Pi-Hole which is supposed to hook up to your router and stop ads from going to every device on the network.
Super easy to setup too, it serves as a Domain Name Server for your home network (the thing that tells your browser that [xyz.com] is at IP address [1.2.3.xxx]) so blocking is super robust because it doesn't allow known malicious domains to resolve. Youtube on a smart tv might still have ads, as Google started serving videos and ads from the same servers to prevent people from selectively blocking.
Hulu did something similar where they started serving pre-roll logos (FX, Fox, ABC, etc.) From their ad server and would only continue the show if that video resolved. So your mileage may vary, but it'll still block tens of thousands of malicious connections
