Is that what you asked her? It's not been my experience with LAX agents, but your experience doesn't sound acceptable.
As far as where you take it now though, I think you'll need to chalk it up to an agent having a bad day or take your business elsewhere. I don't think that AA will share the details of any disciplinary action with you, if that's what you're looking for.
