The applications don't need to know what exact type this object is.

And right so.

It's a pointer, BTW.

I strongly discourage you from relying on internal details of the
FreeType implementation.  We might change them without notice.  You
have been warned now. :-)

FT_LibraryRec is defined in include/freetype/internalftobjs.h.

I'm not aware of such a class, but since I'm not interested in C# this
doesn't mean anything.
