It's impossible to say which runway you'll come in on, and how soon you'll turn onto a taxiway. You may not pass the international terminal at all if you're in a small aircraft (like an A319) that doesn't need as much runway to land on.

If it were me, though, I'd sit on the left, "A" side of the plane. If you come in on one of the north runways, the left side will face the Tom Bradley International Terminal as the plane taxis to the UA concourses. If you come in on the south runways, as the aircraft turns, the A side should get a bit of a view of the TBIT. And if you land on the south runways from the west (over the ocean), you'll get a view of TBIT. Good luck!
