Remember that extract won't be sweet. It simply adds the "essence" flavor of rasberry.
Yes, adding fruit to the primary or secondary is
adding sugar and will continue the fermentation.
If this is your first attempt at this style, I'd say, stick to the original recipe and then "tweak" it with some rasberry to give it a not so obvious hint of rasberry.
The Kolsch recipe is mild so there is not a lot of strong flavor that the rasberry will be competing with. I'd say 1/2-3/4 Oz of rasberry extract into the secondary, then taste at bottling time and see if you need to add more.
