That already happens, in the form of arbitration.

In fact, I'll bet someone makes a bundle selling AI arbitration services that do just that. Got a beef with BigCo? What could be more fair than letting HAL settle the matter?

If I had the sense God gave a gerbil, I'd already have Claude writing up a patent application on this. (Edit, too late: https://www.adr.org/ai-arbitrator/ )
