Hmm, this is not an easy thing.  The syntax you are using is entirely
LaTeX specific, so it will fail in other export backends.
Therefore I am hesitating to put this in as a standard feature.

If you want to have this, you could do the following.  It installs
a function into the export process that will protect such item
bullets from further processing.  The regexp looks quite
complex - this is only because there are 5 different
types of bullets and we also must make sure that a level
1 headline will not be mistaken for a plain list item.
What this really does is finding square brackets at
the beginning of an item, and adding a text property to prevent
further processing.

Hope that does what you need.
