To my knowledge Android TV isn’t any more proprietary than standard Android. The only really proprietary code are the Google Play Services (and Widevine).
Do you mean this konstaKang-Image? LineageOS for the RaspberryPi, I tried that and it works quite ok. A bit sluggish maybe.
LineageOS is an open source project build around the pure open source Android. And the konstaKang-Image is also an open source project, although with a weird license. But they have nothing to do with Android TV, as far as I know.
You can install Android TV on a Raspberry Pi 3, 4 and 5: https://konstakang.com/
Maybe you happen to have one and can try it out.
Does it also include 3b+?
Worth mentioning: Android TV is proprietary and developed by Google. As far as privacy goes it is as bad as any wish.com-android-solution.
The linked build is based on LineageOS, not stock Android. Should be fully FOSS.

You will find the source code of Android, you won’t find the source code of Android TV.
Just like all the Android-based operating systems on smartphones: if you take a free product and add suckyness, the end product sucks.
If there’s no source code for ATV, how can there be (unofficial) LineageOS builds of ATV? Genuine question
