The damages listed in a lawsuit have nothing at all to do with the reasonableness of the parties involved.

By the time a lawsuit is filed you are already deep into a civil dispute, and very few civil disputes ever go to trial. Filing a lawsuit at all is the nuclear option for when all reasonableness has already broken down. You only go to court as the nuclear option after both parties reach an impasse.

15M is almost certainly just a result of mathematically adding up the damages the law provides for. That's how going to court generally works -- your lawyer will ask the court for everything the law provides for. Then the court will decide what is reasonable to actually award. Going to court is very expensive, and it is why ~99% of cases settle before going to court.
