Good point about 'low voltage' -- which does not mean the same thing in all contexts.
>Circuits operating at less than 50 volts shall be installed in a neat and workmanlike manner. Cables shall be supported by the building structure in such a manner that the cable will not be damaged by normal building use.
The only possible violation of 720.11 for duct taping <50V cables to walls I can see is 'neat and workmanlike' which is vague at best; there is nothing intrinsically 'un-neat' about an attachment method unless maybe using like literal chewing gum or something else absurd or just categorically unfit for purpose. I'm hardly going to call it best practice, but duct taping a (small to modest-sized) zip-tied bundle of low voltage cables to say route it up and around a door is perfectly cromulent in my experience.
Likewise I'd feel perfectly comfortable (from both a safety and code/inspection perspective) supergluing cables to dry wall (on the more absurd end), or p clamp'ing w/ drywall screws, or using adhesive zip tie mounts, etc.
