it's not clear to me that cryptographic deniability has much legal
utility.  I wrote about this in more detail last year here:


people get convicted or cleared of things all the time based on digital
evidence that has no cryptographic proof associated with it.
cryptographic deniability doesn't mean that you can cryptographically
prove a message *wasn't* from you; just that your peer can't
cryptographically prove that a message *was* from you.
