Self-hosted TV interface solutions

Hello!

Regarding what Gamers Nexus recently disclosed regarding LG TVs in their latest video I think its finally time to do what I can to mitigate it.

I cant root it since the firmware is too new and I cant afford a new TV either. My best bet would be blocking all LG IPs network-wide and disconnecting it from the network. (Although I understand even that might not be enough, its the best I can do right now)

I was thinking of using an old Raspberry to atleast access youtube and my media server, however I dont know what would be a good OS/distro to run this on. Preferably I would want to use something like an old PS4 controller as the remote.

Anyone here who has any suggestions or living room setups to suggest? Any and all tips are welcome.
