It's easy to make your own.
1. Open the footprint editor, select a similar part, for example the 8x2 header.
2. delete the row you dont want.
3. check the pin numbers are still in sequence, you can edit them if not.
4. move the outline edges to their new position
5. change the library to one of your own so you can keep it if you reinstall Kicad
6. save the part under an new name.
With a bit of practice you will find it very easy to create or edit parts in Kicad.
