From experience, the runway utilisation at LAX usually has arrivals on the outer pair (24R and 25L) and departures from the inner pair (24L and 25R), so landing 24R would be not unusual.
Maybe a better question is where do the QF A380's normally park at LAX? Do they still use the Tom Bradley international terminal, and if so which stands are A380 suitable?
I understand the taxyway issues with the A380, it could be that the parking location determines both the landing runway and departure runway assignation. For example, if they use Tom Bradley northern end then 24R for landing and 24L for departure probably interferes less with other taxying traffic; conversely the southern runways for parking TB southern end.
The northern pair are, however, shorter in length, and hence may be the cause of the requirement for rated thrust usage rather than some degree of derated thrust.
