There's nothing to say Stargirl never existed in the Pre-Crisis Earth-2. We just never met her and she broke the pattern of Earth-2 people sharing actors with their Earth-1 "doppelgangers." We'll have to wait for her show to start to see if Earth-2 is really that different. Earth-2's Laurel is on Earth-Prime with memories restored by J'onn, so she would know the differences if she goes back to Earth-2.
