It depends on the local jurisdiction. Our jurisdiction allows non-licensed installers to install the low voltage lighting (still requires a permit for inspection), if it is hard wired for the line side of the transformer, they have to hire a licensed electrical contractor for that portion of the installation.

We had a heated debate with one of those manufacturers on this subject in this forum (I think) many months back. Seems that because it is low voltage manufacturers think that no codes apply and there also is no safety issue.
Although the NEC sections are minimal, 300.5 gives the minimum cover requirement for buried landscape lighting cable and 411.1 gives the equirements for lighting systems 30 volts or less, these are code requirements.
To answer your question, I think it would be up to the AHJ's in each area as to how they want to deal with this issue. I think I vaguely remember some area requiring landscapers to take a short course and pass a test on these areas which would then allow them to install the lighting.
Reading through the Mass Gen laws I don't see a clear answer. I might tend to agree with him on the assumption that he looked into it before he started this part of his business. I really don't see the need for a license to do this.

Shortcircuit & iwire here in Ma it is legal for a homeowner to pull a permit to install these lights. So the landscaper has the HO pull a permit and he rides off into the sunset with a big wad of cash in his pocket. Just another thing about this state I do not care for.

I can see the occasional landscaper installing some lights and getting away with it,(like going 60 in a 55mph zone)but these guys are engaged in the business of installing these lighting systems for "HIRE" and they are not licensed to do so
You see the key word here in Massachusetts is for "HIRE"(section 3L)...this is what allows homeowners to do there own work.
