Is it normal for Kuaishou recruitment to require payment of agency fees?

Not normal.

Regular recruitment platforms or companies will not require job seekers to pay agency fees. On the contrary, they should provide recruitment services to help job seekers find suitable positions. If you are asked to pay an agency fee, consider it a scammer or a criminal taking advantage of the eagerness of the job seeker to defraud you. Therefore, it is abnormal for Kuaishou recruitment to require agency fees.
