The weapons don't draw energy from the generator; they draw energy from the capacitors because the generator can't give them enough energy.
A LAC just flying along ballistically with wedge and rad shielding up is using most of the energy from the generator. There isn't enough leftover to do what you suggest.
Arguable in terms of towing because otherwise I don't see why Honor would have left pods with the first generation LACs carried by Wayfarer. I will punt on the decoy question, because those have the fusion core of a larger ship to drive them most of the time and no one has told us how much a drone has to weigh or what it's power requirements are to pretend to be a battle cruiser, (Flag in Exile [FiE]) Atlas Liner (Honor Among Enemies [HoE]), or whatever....
So somewhere in the middle... Per "House of Steel", the fission pile is capable of driving the Shrikes and later at about 16% faster than the series 282 used in HoE. The fission pile also charges the capacitors, so let's give it maybe a 50% over power besides the wedge. On another thread, a Mark-16 pod was estimated at 2.2K tons. I'd suspect that's where the 3:1 tow ratio comes from by the way. I'm considering the power budget available for the "LACs plus beta-square nodes" on a ship 1/4 the tonnage of the original HMS Fearless, which was 80 years older and could carry an amount of missiles AND decoys.
So while I'd agree that a LAC is a toy-boat PT-109 equivalent as a tug, aka it can't do anything ELSE, like towing those pods to any effective speed from a standing start, but that's not the argument. All it takes is enough energy to "catch the pods" dropped by the cruiser-- which presumably has got to it's desired point in space and isn't pouring on accel or decel, and the net energy required is zero plus drag at speed only. So it uses it's energy over-budget to achieve that, instead of charging the capacitor banks for the extra shields and weapons.
All the LAC is really doing in this scenario is giving those missile pods an anchor point far enough from the parent cruiser (which is likely still controlling them the same way the GNS Isaiah MacKenzie did at Elric) to trigger a "holy s---, where did those come from?" response in the opp force command structure, and then they're likely playing beat street to fit back into a combined missile defense umbrella -- while using whatever significant portion of the pile's energy they need to charging their capacitor banks to full for the bow wall, stealth and ECM countermeasures, tiny point defense clusters, etc.
