how do you know if that thing is not being used in the project file?

It doesn’t

I take the approach that even if linesStyles are not used, that doesn’t mean they shouldn’t be there.
My general approach is to instead amalgamate all the rouge linestyles into the correct ones.

However, if you were to simply check if the linestyle existed in the proejct and delete it if it was not then you can use this approach. (Gets All Lines, Gets All Lines in Project for Each Subcategory, if the list of lines in the project for the subcategory is empty, then it it un-used. Filter the Subcat list by that boolean and then delete the resulting subcategories.
