Metrolink won't help you very much. It is the Ontario stop for the Riverside line but it is on the side of the airport away from the terminals and there is really no way to get from one to the other. And Metrolink runs from Union Station in downtown LA which is a long way from Santa Monica.
If you don't want to rent a car, then you might think about SuperShuttle -- you can actually book it online supershuttle.com. Probably cost you about $60 each way.
If you do find something that works, let me know.
