If I were you I'd keep a close eye on the ETA for your flight before checking in at LAX on the day of departure. It may also be worth watching the incoming flight, as that may give you advance clues as to whether your flight will be late. If there's a reasonable chance of a delay, you could make a good argument that you'd much rather that your LHR-AMS flight be changed to the next day. Hey, you may even get BA to spring for a hotel in London lol. You already have a razor-thin margin before your connection time falls below the MCT for LHR T5, so all you really need is just a small projected late ETA at LHR.
