Other mistake: Black Widow and her sister steal a BMW. Getting away they damage the left rear quarter. A few cuts later they show the car again and it has no damage to the left rear quarter. (00:40:15)
Other mistake: During the opening scene when the family is driving down the road, various gas stations can be seen with prices typical for the era in the low single dollars. But during one brief shot through the rear glass, a modern price of nearly $2.50 is seen.
Chosen answer: Are you talking about the woman who has the mind control antidote that ends up freeing Yelena from the Red Room's control? She's a rogue ex-Widow named Oksana played by martial artist and stunt coordinator Michelle Lee.

That's her. It's only a semi-resemblance, but was close enough that I basically assumed if that was Olga Kurylenko she'd had her role cut down, or was a cameo, or might appear in flashbacks. Either way I didn't spend the film thinking "when's Olga Kurylenko showing up?", and anyone asking that of themselves presumably might figure out who was playing Taskmaster before the big reveal. I might just be overthinking it of course. :-).

I actually thought it might have been Olga Kurylenko at first as well.
