There are lots of good reasons that are used to paper over the abuse cases.
Microphones in tvs are a useful accessibility feature when they enable voice commands for the user, and allow them to be used as voice assistants.
They also enable tvs with a camera and microphone to be used as video calling or audio calling interfaces. Used well we get star Trek view screens, used poorly we get little brother monitoring.
For those interested, it turns the tv into an interactive terminal for voice and camera powered video games, which are becoming more popular.
Unfortunately advertising and tracking incentives drive the abuse cases to the top and will crush the positive use cases :(
There's no practical reason for most people. Spying is the primary function. Edge cases like accessibility or conferencing can be easily enabled with an add on USB mic. You'd need a USB webcam with mic for conferencing anyway.

Made nearly moot by the presence of microphones in most (all?) modern remotes.
I say nearly moot because its worth noting the ability to operate a physical remote may itself be prohibitive to some.
So in effect, there are a multitude microphones in a modern LG environment.
Are there any useful resources for finding devices that don't have surveillance apparatus built in?
I'm still not purchasing a television. The last thing I need is more screen time in my life.
