I agree with this, and Gargantuan Creatures do indeed have a special rule otherwise. But let's explore an alternative, where a "shooting attack" is just a single set of named weapons from a unit firing at a target.
If that were the case, it wouldn't make sense for Pinpoint to say "for the duration of the shooting attack". Since only one set of named weapons in the unit is being fired, it doesn't have much of a duration.
It would also mean the Stormsurge's anchor rule would let it fire a weapon at one unit, and immediately fire it again at the same or a different unit. I believe the current ruling in FAQs and the ITC is that Gargantuan Creatures must declare all attacks and resolve them. In the case of the Stormsurge's anchors, it declares the first set of attacks, and then can declare the second separately once the first has been resolved.
Edit: In addition, "for the duration of the shooting attack" means that Pinpoint only affects one set of named weapons for the unit. Other weapons shot don't get the bonus, even if they were firing at the same unit. That does not seem to be RAI.
It's not a slam dunk, but it does appear to fit better if '"shooting attack' equals shooting once with all normally allowed weapons". Circling back, this means Pinpoint's bonus applies to all weapons on a model fired at any target, as long as at least one of them was fired at a unit with markerlights to remove. It also means that bonus does not carry over to the Stormsurge's second set of shots.
After looking over the latest draft FAQ:
Each markerlight counter is spent to provide a specific bonus or affect against a single unit
The question being answered was about Split Fire, but this sentence would clearly affect how Gargantuan Creatures shoot with markerlights. So if the draft FAQ is in effect, then you can't boost the Stormsurge's attacks on other units this way.
Interestingly, it would still mean the Pinpoint bonus does not carry over into the second shooting attack by a Stormsurge. This ruling nerfs the Stormsurge.
