Undoubtably, the airline doesn’t allow them to help because of “lawsuit”

And while I agree, they should have had the wheelchair there in the first place, I don’t see that as the core problem. While this incident wouldn’t have happened if the wheelchair were there, there will always be problems that need to be addressed in real time while running their business.

This incident shows how they respond to problems and it is terrifying. Sure, the company could make sure there are wheelchairs on every plane so that this particular incident never happens again. But the broader issue is that they appear to have actively disempowered their employees from solving problems or doing anything outside their specific list of duties. Problems will always happen and you can’t have a precise plan for every possible problem. That’s whey employees need the power to solve those problems. Otherwise you get evil shit happening like this.

Edit: and the solution was simple. If you don’t have the wheelchair you are required to have, you wait for a wheelchair (or give the passenger get the option to be physically assisted off). Yes, that is painful to the business. It means delays. But that is the obvious solution.
