There is a section in the documentation that mentions "<TMPL_LOOP>s within <TMPL_LOOP>s are fine and work as you would expect."

This is untested but should get you going in the right direction:

in your script

$template->param( 
  STATE_LOOP => [
     { state => 'Alaska',
       NAME_LOOP => [
         { name =>'Judy Jetson'},
         { name =>'Barney Rubble' },
       ],
     },
     { state => 'TEXAS',
       NAME_LOOP => [
         { name =>'Joe Bloe'},
         { name =>'Jane Doe' },
       ],
     },
  ],
 );

and then in your TEMPLATE:
<ul>
<TMPL_LOOP NAME="STATE_LOOP">
  <li><TMPL_VAR NAME="state">
     <ul>
     <TMPL_LOOP NAME="NAME_LOOP">
       <li><TMPL_VAR NAME="name"></li>
     </TMPL_LOOP>
     </ul>
  </li>
</TMPL_LOOP>
</ul>

This will probably need some tweaking.. but should give you an idea of how to proceed.
