I believe this is a known issue since the beginning of VCMP, but we never had a productive discussion about it.
A lot of GTAVC skins, who are short in height(especially females) appear too fast in VCMP. Do they only appear fast, or are their animations/move speed faster? If someone is into skin modding, maybe they can provide an insight about the bones and animation data. The lady carrying shopping bags seems to be the hardest skin to hit, or maybe it is just the visuals which makes the movement hard to judge.
Also, their hitboxes would be smaller compared to other skins, so hitting them should theoretically be harder.
It is quite common to see people using these skins in DM servers for the slight advantage. I wonder if it is possible to fix these skins and use custom female skins on DM servers(or outright delete female skins from every DM server).
