Yes there is ... there is a couple of old threads and at least two mods to enable surface ships to launch torpedos. From what I remember it was a list of DD's that could fire them.
If the DD can fire them anything can.

... Can all fire Torpedoes with the "More DDs for AITorpedoLauncher" mod from what I read.

I would compare it to
jhapprich 's mod and see how they work then add them to other ships as well.
