I read project readme, checked client side and server side configurations, and no such feature exists - YES

Is your feature request related to a problem? Please describe.
Not a problem.

Describe the solution you'd like
Could Illagers be made to use the same weapons/animations as the player?

Sorry to crack open an issue on what is essentially a comment, so feel free to close as appropriate.

Sorry it is not possible. The depended animation library doesn't support animating mobs.
