While theoretically the second option is possible (heck i can even put together a route to get me from thousand oaks to LAX by public transport), you can not seriously suggest smth of that nature to OP or any visitor to LA.
Flyaway bus actually may be an option if schedule works however it probably does not fall into public transport category (at least not any more than hotel shuttles or supershuttle etc). For two or more people rental car is gonna be competitive pricewise and offer far more flexibility though.
