Yes, they are illegal. They are not 'aimed' for left hand driving, the cutoff pattern is designed for left hand driving. Some people install JDM projectors and just aim them lower without doing the conversion, since they have a greater adjustable range than USDMs. Furthermore, modifying your headlights is illegal in most states until you get a DOT sticker put on them after you modify them. But if you convert them to UDSM light patterns and aim them correctly most likely no one is going to bother you.
However, your thread is about the fog lights. The fog lights (as far as I know) do not have a cutoff pattern like headlights, so JDM foglights will not need any modification. They aren't meant to shoot out light far out like headlights, they are meant to light the immediate area around your car.
