Probably the former, since the show already established (in the scene at the resort where SM-33 gets a restraining bolt) that droids have been used as weapons. That may seem like a no-brainer to long-term fans that are very familiar with battle droids and assassin droids, but try and look at it from the perspective of making sure this show makes sense to someone that's never seen a Star Wars anything before. That they took the time to point that out (even after SM-33's multiple rampages) means they want the audience to have this information, so it'll likely come up.
Indeed given how much that was set-up in just the first episode has paid off so far (overriding droid memory, KB's voice modulator, even "unclaimsies!"), it'd be strange if this also didn't lead to something, just like the cannon on the At Achrann school building, and the repeated inclusion of slapball will almost certainly come into play.
