Agree with the problem being with the shop NOT Scott.
As far as I can see everything 2014-2015 in 700-740 flavor comes with 15mm fork.
Mismatched grips sound to me like the bike has been built up before.
Scotts retail packaging is careful and very good.
Bike come with a ziploc bag FULL of manuals, warning labels tied to the frame and all that jazz. I’ve never seen (as far as I remember) a bike come with allen keys.
I’d suggest that the bike you have purchased was either a sample, or was a shop floor model that has had parts butchered.
Do all your fork stickers, grip colours, lock out cable colours etc co-ordinate with the frame colours?
Your issue is with the shop.
