You have to use "saveAmberParmPol" to create prmtop files for polarizable
force fields.

...hope this helps. It should be simpler, but Amber has *very* minimal
support for polarizable force fields, and ff02pol is more than a decade
old. There is some effort towards developmentof a new polarizable force
field, and its use will probably be simplified (and better documented)
once more users start trying to use it.

(Aside: Amber also supports Amoeba, but that it done by a very different
mechanism that does not involve LEaP.)
