Aircraft X was on final approach landing LGB. Unknown VFR traffic was transitioning through LGB Class Delta climbed to 1500 feet opposite direction just north of the final approach course. I issued a traffic alert to Aircraft X who promptly reported the traffic in sight. A mile later; they reported that they were responding to a TCAS/RA climbed to 3000 feet and were sent around. The VFR target later went through SNA airspace and I had them issue the brasher. The LGB Tower Controller was talking to the unknown VFR target but let them fly opposite direction in close proximity to the final approach course. They called traffic but let the targets converge and terminated communication with the VFR aircraft instead of giving them a frequency or ensuring that he would not be a factor. LGB needs a Class C Airspace or at least better VFR departure procedures.
TRACON Controller reported an air carrier on short final received a TCAS/RA and initiated a go-around for a VFR aircraft flying on the final approach course.
