Here’s some issues I found with your log that might help.

do i need a 3ds to do this?

Yes.
If you want to use Citra you at least need to own the game. For digital (CIA) games you need a 3DS which you used to actually buy the game from the eShop. For cartridge games you can ask a friend to help you dump your game.
Obtaining the games any other way (like downloading them from shady websites) is illegal and not supported by Citra of course.
