No, there will be no issue with that. A few years ago, I had to leave the airside area to dash back to the airport hotel where I had forgotten to pick up a package mailed to me. I came back airside with the same BP.
AA at LAX does not have any limits regarding how early you can check the bags on the day. You can drop yours and then leave the airport. I'd probably check the bags in the general check-in area (there is a Priority line as well) to avoid questions why you're not continuing to security at the Flagship check-in (not that I think it'll be an issue).
