I think it depends on how the car ran over the children (or anyone in that case). If it was an unavoidable freak accident, then you can't really blame the car.
But, if the car literally didn't see a person in front of it (where reasonably a human would 99.9999% of the time) because it's cameras malfunctioned or the LLM read it as something else, then those cars should not be on the road.
