I hope legislation is never manipulated enough to allow an AI to form a corporation or become it's legal director. With whom would accountability rest? Who would you throw in prison if it acts egregiously enough to warrant such a measure? If it's bots all the way down.
Corporations already exist to limit liability and accountability. This would be an extension of their current purpose not some weird deviation from.

It would be useless, given that you can just install a human controller signing (or not) decisions from others: the human remains responsible.
