To re-iterate what was said above, give yourself more time. Here is my personal experience not LAX but SFO. We had two hours between flights, but then there was weather (fog) at SFO so the departure was set back ~30-40 minutes. Workable. We boarded then sat on the tarmac for another 30 minutes. Okay cutting it close. We land, exit the plane with ~35 minutes til departure, and run/walk from one terminal to another. The security lines is a mess. We walk right up to the front and get through. We get to the boarding with ~15 minutes to spare. BUT remember boarding closes 15 minutes before departure. So yeah we made it. Everything was booked on single ticket so we would have been safe had we missed the flight. But that is not your case and there are horror stories of people having to buy a new ticket after missing their onward flights.
