I don't think so. OP couldn't check in and wasn't able to go through TSA security until after DL in another terminal had rebooked him and reissued the ticket for the LX flights, so that he could then check in with LX and proceed to that gate. By that time, the original AF LAX-CDG flight had left long ago.
Of course it's silly, but that's what the rules seem to say.
