As far i read you cannot use LiteSpeed Enterprise yet on aapanel, even if is the free 2gb edition.
Most noticeable differences between OpenLiteSpeed and LiteSpeed Enterprise is LSWS has fully .htaccess support while OpenLiteSpeed only support REWRITE RULES and you need restart web server everytime you change something in the .htaccess also LiteSpeed Enterprise has a nicely rate limiter to wp-admin zone, and i know this can be done in other ways but is cool having in just to one click.
