The nihilists didn't really kidnap anyone, and the girlfriend willingly cut off her own toe.

Jeffrey Lebowski hoped Bunny would be killed by the kidnappers when he gave The Dude the ringer, but there was no kidnapping victim to be murdered.

Bunny didn't stage a kidnapping on herself, she was visiting friends in Palm Springs and completely unaware of any kidnapping plots going on.

Walter didn't really steal the million dollars, because he threw out the ringer for a ringer.

Maude tricked The Dude into helping her conceive, but she explicitly doesn't want his help raising the child. Also she did break into his place and have him punched on the jaw, but since she got him a check up with the doctor afterwards and the rug was a gift from Maude to her late mother and not for her father to give I guess that balances out.
