If I bought a plane with training included and had not completed the training I would not go flying in it. My decision. To collect in such a suit I'd expect to have to show (probability) that the training was deficient. Difficult to show due diligence and duty of care if I was flying at 100 ft or so 'by moonlight.'
This is a jury award and USA juries are notorious for their "Well someone died and we feel sorry for the families, so someone must pay vast amounts," type awards, (and that is a generic comment and may have no relevance to this or any particular case.) These are often modified on appeal where a judge may change everything, however that in itself can be expensive, even if you win.
