OK, this is clear.
This could be (partially) resolved with my proposal:

<dtml-in "ZOPE.objectValues(['KBFolder', 'KBItem])">
   <dtml-if "_['sequence-item'].meta_type=='KBFolder'">
       <dtml-in "_.sequence-item.objectValues(['KBItem'])>
            <dtml-var sequence-item>
       </dtml-in>
   <dtml-else>
       <dtml-var sequence-item>
   </dtml-if>
</dtml-in>

[notes: 
this is only to give the idea. It is not tested.
1. It would need some elaboration for more than 1 item deep (by
factoring out the dtml-if, for example
2. Though I did not try this, I'm sure you could also do this with
KBFolders returned from a Catalog]
