LAX needs you have a transponder so they may collect their money
To get a transponder you need to leave a deposit of 50.00 plus a" yearly membership" of 150.00
Also, a Los Angeles license (free I guess I dont recall) But you need to report your gross every year.
Probably LAX will waive TCP.
But, they cannot waive a non exclusive contract between you and LAX....which requires certain Insurance where LAX is covered for any incident inside airport....
Unless they wave all of above stuff it wont be a big deal to be able pick up at LAX.
