Say I have a file directory with hundreds of modules, I want to know if
there is a tool I can scan and identify the uninitalized variables in all
the files once (or through a loop) without actually running through all the
pages.

"use strict" will find the undeclared/undefined variables.
something like
my $var;
and later on used in the program will not be find by the "use strict",
but
will cause "use uninitialized variables" warnings if -w switch is on.
If you really want to cause your scripts to crash on every
uninitialized variable so you have to go in and fix it, you can do this:
use warnings FATAL => 'uninitialized';
