I’d probably do something that’s a large dial like an Apple Watch crown for volume that takes up most of a square remote and you push down for mute/unmute. The other buttons I’d have on it would be power, and input switch. I’d have an Apple HomePod sound bar which connects to the tv so you don’t have to configure any of that. Then you’d use the Apple TV remote like normal for everything else. The regular dial remote is just always sitting on the coffee table. Alternatively they could extend the existing Apple TV remote a bit to add a mute and volume knob or reconfigure to be the one remote for the dumb tv and the Apple TV.
