Yep. Both the intersection American 106 was supposed to take (cross 31L at K) and the intersection they took (cross 4L at J) have runway entrance lights.

According to https://www.faa.gov/air_traffic/technology/rwsl/pet/ the lights don't illuminate until departing aircraft are at 30 knots, so it's possible Delta 1943 was just beginning the takeoff roll and the lights weren't on yet when American 106 decided to cross 4L.
