It's hard to know for sure, but the majority of these flights are probably going to be transfers. I've never set foot in LA but I've taken that flight several times.
Even so, there are only ~20k daily seats between the two cities. The ridership on successful high speed rail lines elsewhere in the world are measured in the hundreds of thousands per day.
Why couldn't one part of the journey be by rail, and the other by air? There is a already a lot of shared planning to allow this to happen, with some railway stations even having IATA codes.
