Definitely not a Krusty Krab

If I want to avoid connecting my LG smart TV with my network, but I would like to still use a remote with an external device running Jellyfin plugged in via HDMI, what privacy respecting options do I have here? AFAIK, TV sticks run Android and can also collect your data, so my natural guess would be to plug in a device running Linux, but how about remote control?
