Fastest way to create child class from parent?
Well, I didn't want to post yesterday since this was an 8-year necro, but if it's becoming an actual discussion again, what's wrong with simply creating a new class, setting inheritance via the Properties page, and then choosing New > VI for Override from the right click menu (on the class) and then holding shift whilst selecting the VIs to override (all of them, in the example described).
It seems likely that the key point is (was)? as Intaris is pointing at here:

... inheriting from a class with concrete implementations of methods to override those concrete methods can be tricky. Typically, one would create an intermediate class with "abstract" methods which children can override. There ARE cases where it's legitimate though.
If the class to be copied has concrete implementations, and you want to make small edits to that code but still basically keep most of the implementation, you'd be better in my opinion creating a subVI in the relevant methods that was dynamic dispatch and using the Template pattern (Implementation in LabVIEW by Elijah Kerry, wiki, refactoring.guru) to allow a new child of your existing class to only change that bit (perhaps providing the concrete implementation in the existing class (i.e. via selection and Create SubVI) and then just overriding and not using the Call Parent Node).
If you have concrete implementations but you don't want to copy the implementation, but you'd rather have a new "sibling-like" class with an alternative (completely different) implementation, what you need is a parent class (ideally abstract, as Intaris mentioned). To create one of these more easily in LabVIEW, take a look at Sam Taggart's Class Refactoring Tools, which include a right click option to create an interface class (the tools predate 2020, so this will as far as I know still be a class, not an interface).
