Which airline are you connecting with at LAX and is it on the same ticket? There are 9 terminals at Lax you will mostly land at Tom Bradley Terminal which most international flights land at.
We landed at 19.30 and made our flight in plenty in time. at 22.30 from Terminal 6 though arrivals was quiet. I have heard of long queues at Arrivals bit like MCO but depends how many flights land at the same time, make sure you give yourselves plenty of time.
Lax is a big horseshoe with TB in the middle. You can walk between each Terminal and there is a bus which goes around to transfer Terminals.
Hope this helps.
