This is like, someone steals my car, so I burn down their house and murder their whole family. I can't imagine a case where 15M isn't destroying someone's entire life.
No, asking a court for a large amount of damages from an LLC is not in any way similar to arson and murder.
I don't think they expect to actually get 15M from this suit. Honestly, it seems like they wanted to avoid the suit altogether, because of how it looks from a PR POV.
