I feel like prompt injection should be a perfectly legal defense but only as long as it‘s phrased reasonably. Or is adding a note that asks for a fair trial unreasonable enough to be dismissed? When you only try to reason with unreasonable word salad how could anyone blame you for it?

Adding to that if one side uses LLMs they should definitely have to at least attach the prompts they used and share what model they used so it can be replicated.
