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 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
