If I were you, I would just stay at airport, do some shopping. Your time is 6-11pm, it's already dark, and the traffic around LAX is very very bad..... beach area is very cold in the evening, and you see nothing, also the safty is a big concern....
Unless you have a good friend who can pick you up, go somewhere for a good chinese dinner.... otherwise, don't go anythere....
