The AA/DST toys for Enterprise and Nemesis came out during the show's production i.e. "during that time period" so they could have been included.
Star Trek isn't just TOS, the majority of fans today would be in the TNG-ENT bracket, so the Toys that Made Them would be those that came out during the 80s and 90s, possibly early to mid 2000s too. Granted the show was mostly focused on talking to fans in their 50s so the toys that made them would be the 70s junk. It was a missed opportunity to interview fans in their 20s and 30s, who would have had nostalgia for the wider range of Trek toys.
