I don't take pleasure in defending an AI company, and I'm not a lawyer, but I doubt she'd have case here. The AI tool is just a tool (and one based on probabilistic algorithms). She should sue whatever parts of the "justice" system misused the tool.

If a cop wrongfully shoots someone, and it's the cop's fault (i.e. not a gun malfunction), I would guess that it would be hard to sue the gun manufacturer instead of the police department.
