In my various neck(s) of the woods the low-voltage lighting ends up being cord and plug connected and in many cases not afforded the joyous opportunity to be inspected by anyone other than the home owner right before they pay their bill. However, you did state something regarding low-voltage lighting near pools to which the local inspector would indeed cite any issues with Article 411 and 680 respectfully.
The real issue is that the NEC mandates one thing but the permitting process in a local jurisdiction may mandate yet another. For example, in some localities you do not need a permit for anything under 50V that does not penetrate a fire rated assemble and such...so no one would ever pull the permit for the low voltage lighting to even get inspection.
This does not excuse someone from following the NEC where applicable, it just means no AHJ will be charged to observe it and make judgment on it. If any of that makes sense, I hope it does anyway.
