Narrative:

Lax tower instructed our flight to cross runway 24L and hold short runway 24R at taxiway V. Tower then requested a 180 degree turn in order to hold short runway 24L at taxiway V. Captain transmitted that we could comply and added power to start aircraft rolling. Aircraft rolled over hold short line to runway 24R. I simultaneously informed him that we had an aircraft on final for runway 24R. We stopped with our aircraft partially over hold short line for runway 24R. We informed tower that we needed approach end of runway 24R to accomplish 180 degree turn. They approved request and we exited runway 24R with final approach aircraft at 2 NM. Solution: don't move the aircraft until you're sure that you can maneuver as requested. I should have been more proactive to let the captain know that he is not cleared on any part of runway 24R.
