It's up to the local jurisdiction to enforce what part of the NEC they see fit.
In my state the only licensing need is for security and I'm "assuming" that if lamp cord is only being used as "low voltage" wiring then their would be no violation of any NEC code.
The licensing requirement has nothing to do with code requirements for your area/state. NFPA 70("The NEC") covers anything electronic permanently and occasionally temporarily installed in dwellings, buildings, outdoors, basically anywhere. It varies from state to state as to what is enforced, but pretty much nationwide the NEC has been adopted as the standard. I would suggest that anybody performing low voltage work pick up a copy. Most low volt guys assume that because they only do low volt the NEC does not apply but if you look, there is an entire chapter dedicated to "communications circuits", ie: phone, data, catv, signaling circuits(automation), etc. All of the codes regarding CL2, CL3, and plenum type wires and applications are listed.
Having said that, sadly most inspectors don't give a rats about low voltage.
