As you fly over the San Bernadino mountains, you should be able to see the Big Bear ski area (not much compared to other major ski areas in the Rockies) and Catalina Island from the left side. Once you are over, you should be able to see the Ontario Motor Speedway and Mount Wilson radio and TV towers on the right side, in addition to the others already mentioned. Most of the flights I've taken landed on runway 24R, so you will be flying close to the Hollywood Park race track and Inglewood Forum and over the hamburger place, In & Out, just before touchdown and can see it from the right side.
These aren't much of attractions, but I thought I'd add them. Most of these should be visible regardless of the weather except for the ski area, Mt. Wilson and Catalina Island. The others should be visible since you will already be under the cloud cover or close enough to the ground. This time of the year is the rainy season so take that into consideration and check the weather.
