Narrative:

Aircraft X departed lax runway 25 complex on the OSHNN7 RNAV SID. On initial contact; I turned aircraft X to heading 190 to shorten the route for his flight and climb reference other traffic. I observed aircraft Y; appear to be deviating from the runway 24 complex departure course for the DARRK1 RNAV SID. I advised the malibu radar controller; who was responsible for aircraft Y that aircraft Y appeared to be deviating and immediately issued a safety alert to aircraft X and advised a left turn to heading 160. Aircraft X reported aircraft Y in sight.this has happened multiple times since the implementation of metropolitan-plex. These conflicts keep reoccurring and are an imminent safety threat.
