We recently blacklisted some of the IP’s that our LG tv was sending data to. I can’t believe the sheer number of requests logged in just 1 week! And what’s worse is LG is even denying it now

I can only recommend everybody that has the option for it to run adguard home as a DNS server.
It if you already have a PiHole that can do the same trick. Adguard has support for all DNS protocols and forces itself into windows and android via DoH and DoQuick.
A friend of mine maintains a list of blocklist here: https://github.com/ppfeufer/adguard-filter-list

I run PiHole too, but note Adguard/PiHole do not block DNS over HTTP. If these Smart TV’s want to get nasty, and they already have beyond expectations, they could employ that tech or hardcore IP addresses.

If the Smart TV uses and hardcoded http DNS server, that must be blocked directly, sure. But that scenario is very unlikely.

They already do this. They have fallbacks, but is documented that they do this.

Seems like it might be easiest to set up a dummy server. Let the device think it reached home.

I would think that a CA certificate may be hardcoded? Only way it to block it. Faking it maybe with rooting. And then you can gut it also
