I believe the judicial system does do the fine as you mentioned, but the prosecutors have to be realistic and settle out of court at the risk a skeptical judge/jury.
Without LLC laws, you could go after personal ownership too. Privately owned company means there is a few billionaires to have their wealth confiscated. Publicly, our 401ks empty + risk of losing our homes.
Isn't that insane to think about? What would a world look like if that was the case. Would companies be incredibly responsible? Would investors be incredibly responsible?
I don't claim to say this is the best economic system, but it might solve our climate crisis by forcing people to be liable for themselves and what they own.
