BugZilla is written as plain Perl CGI, so it should work well with LiteSpeed.
In addition to the step in our cPanel guide, you need to add a script handler for ".pl" at server level, just use CGI as handler. restart LiteSpeed, it should work.

You can try our persistent perl daemon to improve performance as well, but it is not guaranteed to be working 100%, as it also depends on the perl script.

If those are too much for you to handle, we have installation service available for $149. :-)
