I released Aircraft X from LVK airport on the LVK3 departure. The aircraft checked in 018 climbing to 040 on the departure procedure. I asked him to IDENT and issued traffic 1 mile away indicating 036. I told the aircraft radar contact and issued a turn to heading of 360 and climbed the aircraft to 100 when the aircraft was leaving 026. I had to reissue the turn and climb to the aircraft for additional traffic that was along his course at 029 indicated. The aircraft then advised that he was responding to an RA and descended into a 038 MVA to 022 when I issued a 'Low Altitude Alert' to the aircraft before Aircraft X started a climb to 100.LVK airport is in a valley with no radar/radio coverage to approach control you cannot talk to the aircraft until almost 020 with the aircraft climbing to 040 on the departure procedure. I recommend they expand the Delta to 4000 to the north to protect the departures from the airport.
NorCal TRACON Controller reported an unsafe situation with a departure off of Livermore airport.
