I have run into the same problem, and have discovered a workaround. I have a Google Pixel 7a, so always connected to a Google account. And YouTube on my LG UJ6300 is logged into the same account. With both devices on the same wifi, when I run the YouTube app on both devices, the phone offers to connect both devices. I then see the comments and other options (including the like and dislike buttons) on my phone that relate to whatever video is playing on the TV. The like and dislike buttons on the phone work as expected, whereas they are still non-functional on the TV's app.
It's not ideal, but at least it gives me some means of training YouTube's algorithm with my interests.
