As there is only 1 LAX-LHR daily, any valid options would need to be 1 or more connections. So you would need inventory availability on each of those flights (some well before the 24-hour window). SDCing in those cases can be more challenging (especially for deep discount fares).
As for standby, you can not standby for a later flight, only earlier.
