Thanks for providing your list. I've dug a little further and for me the chain to List::Util appears to be just File::Copy -> Scalar::Util -> List::Util with File::Copy having this line:

my $Scalar_Util_loaded = eval q{ require Scalar::Util; require overloa
+d; 1 };

This explains why I'm seeing it but not why it is absent in your case. I'll leave that part to you. :-)
