They might not all run back independently, piled up with ring terminals. And they probably don't. Most likely the grounds are crimped together along the way, or use a buss block, and then routed back to the negative terminal using a thicker wire to carry the amps. But all the grounds need to get back to the negative terminal somehow. Can't comment on the aluminum frame thing. I know aluminum conducts electricity, just not sure how well. Often electrical problems are due to poor grounds which is why it might not be the recommended grounding method vs copper wire
