It does make sense. :-)
The second word in the term refers to the location of the target, not the path of the missile. So a land-to-air missile is one designed to destroy aircraft or other missiles. And yes, there are air-to-land missiles, fired from aircraft at targets on the ground. They can be aimed much more accurately than a conventional free-fall bomb.
More seriously though, I wonder if North Korea is exploiting the world's focus on the pandemic deflects attention from the country's armaments developments. Those developments would probably go ahead anyway, and because it takes an appreciable time to design and develop complex items like guided-missiles, are probably within a programme started well before Corvid-19 appeared.
