There's no protocol for that over Bluetooth. One could be created, but it hasn't been yet. Nor for relaying data. These don't exist. Like, there are limited relays like what iPhones do for AirTags, but not for a vacuum cleaner to transfer data via your fridge to your neighbor's open WiFi.
In every case where someone's TV has mysteriously connected to a neighbor's WiFi, it's kids or the babysitter or someone else who actively tried to connect to watch a show.
I think you’re probably right but I just wouldn’t say it as confidently as you do. There doesn’t need to be a specific protocol if the manufacturers are in cahoots (and there’s plenty of reason for them to be) they make their own and obfuscate it amongst all the other things these devices do.
So maybe it's not BT, that was only an example theory. It also doesn't need to be always running, so could be harder to track. What if it turns out it's just some high pitch inaudible sound using morse code... I could go on but I'm not trying to crack the case - my point is that things like this that you assert don't exist, often do to turn out to exist on a long enough timescale. I remember reading a lot of tin foil hat theories on various things that some people asserted were illegal or simply impossible; then a decade later Snowden proved the theories right. It seems like these things happen regularly these days.
