So you would need to make case against LH that they neglected to prepare for such an IT incident and did not do enough to prevent such a failure. IMHO one can rant about this but I do not see any chance to win such an argument.
Within our organization (responsible for critical infrastructure, just as LH) we host our most critical system on locations across Europe with an overnight failover as a realistic option. Each of the locations has multiple data centers within one metro area to provide solutions for minor failures. That‘s called prudent planning for critical infrastructure.
