Narrative:

Air carrier X waiting on the concrete pad at runway 24L at lax, tower cleared us onto the runway. I acknowledged, 'we will taxi onto the runway.' while taxiing forward, I told the captain to 'hold on,' when I observed a commuter coming in for a landing on runway 24L. The captain thought I was saying hold on for a widebody transport landing on runway 24R. I told the captain to 'stop.' he did, but he was probably 20-30 ft past the hold short line. I could still see the line out of my window. Several seconds passed, then tower sent air carrier Y around. We were 20-30 ft from actually being on the runway. After another couple of mins, tower cleared us for takeoff. Supplemental information from acn 212784: as we were moving toward the 'hold short line,' tower told us to taxi into position and hold. We responded with full call sign and readback. As we moved very slowly past the 'hold short line' the first officer checked final approach for runway 24L and saw an light transport 1/4 - 1/2 mi final. He said 'stop.' I looked past the first officer and saw the aircraft and gently stopped. We were short of the runway but past the 'hold short line.' tower told air carrier Y to go around. He told us again to 'taxi into position and hold' and then cleared us for takeoff.
