There could arguably be offenses relating to the "attempted promotion" of prostitution that dont come under 101(a)(43)(K)(i)which deploys 4 verbs:  "owning, controlling, managing or supervising of a prostitution business." Those are specific verbs, seemingly aimed at the top end of the enterprise. Not everyone who has ever been involved with the prostitution business has "owned, controlled," etc; so there might be a statutory argument that an offense such as employment at a house of prostitution (i.e. as a receptionist) is not an aggravated felony.
