No, but their heirs can.'s not like that's a special problem for GMO foods. People die all the time from all kinds of torts, and their heirs sue the tortfeasors. We have no problem dealing with that through the normal operation of courts.

"Do you believe rat poison should carry no precautionary label?"

If I sell you some food product on the understanding that it's, say, orange juice, and it turns out to be rat poison, (1) I have defrauded you, which entitles you to get your money back, and (2) if you consume the rat poison and die, it's no different than if I had slipped rat poison into your drink at a restaurant - i.e. I murdered you and am liable (this is assuming I knew, or should have known, that it was rat poison).
