April 2021 Update: The Getty reopens in late May
The Getty Center presents the Getty's collection of Western art from the Middle Ages to the present against a backdrop of dramatic architecture, tranquil gardens, and breathtaking views. There is also a nice garden to enjoy, and it's a great place to spend an afternoon. Admission to the museum is free. There is a charge for parking, which does not apply if you are taking the bus.
The Getty has limited hours (see their website for a schedule), and can be quite crowded on weekends. Admission is free.
From LAX, a bus ride takes 90-120 minutes each way (including transfers).

It could take 4 or 5 hours to see everything. Also, you might enjoy sitting in the garden or on the grass for a little while. So you will realistically need at least a 8 hour layover for this excursion. Don't forget to allow an additional hour to get through security and walking through the terminal at LAX.
