That's interesting. I think the bikes-facing-left bias probably comes from how humans use bikes: the kickstand is on the left, so people likely hold and approach bikes from its left.
Looking online, the kickstand is apparently on the left to avoid the gears. Based on the other comment about bike photography, it's interesting the same design choice makes humans and cameras/LLMs see bikes from different sides.
