I hate that this is how AI is being used.. but tbh this is a nothing burger...
This is exactly what a good lawyer/team does.. they argue against what their client is accused of.
a good prosecutor should be able to dismantle the AI argument the same way they would a human argument. just because its AI generated doesn't mean its a corrupting of the process or cheating..
the process is the same either way, its corrupt or broken the same way either way, it works the same way either way.
This was an EXPERT WITNESS, not an advocate. Though unfortunately (and bizarrely) it appears that in the US, expert witnesses in civil cases can be hired to say whatever the hiring party wants them to say without it being perjury.
