My Zoe’s back pocket is like that, curves outward just slightly. I don’t use the back pocket but I’m sure daily stretching would make it stick out more. You can find in older models of bags and wallets, especially in the curved-edge-flap card holders, LV’s canvas just does that. I remember wanting the last white multicolour card holder but it was bent sitting on display.
My guess is that monogram is printed onto a biased canvas for assembly. Actually, the little serration lines underneath monogram print shows this angling. Print looks upright but the canvas itself is angled to hug properly in cutout and for assembly.
