Narrative:
Departed lax for smo. Lax departure control turned aircraft X to the downwind level at 4000 ft and switched the aircraft to me. I observed a 4300 ft VFR target exiting the lax special flight rules area descending. Both aircraft were on a collision course. I called a traffic alert and the pilot told me he had the aircraft in sight and was descending to avoid it. After the targets passed, the pilot informed me that he also responded to an RA (TCASII). Had he not descended, they would have hit.
