Is a County Prosecuting Attorney either required or authorized to provide legal advice and representation to a rural library district or a regional library composed of a rural library district and a city library?

An informal AGO Opinion issued 11/12/1976, signed by Deputy Attorney General Philip H. Austin and addressed to Jeffrey C. Sullivan, states:

“Your question is answered in the negative… This office [has] characterized a rural county library district as an independent political subdivision rather than, merely, a county agency… We concluded that the prosecuting attorney was required to provide legal representation [to] county agencies rather than independent municipal corporations… Those duties and functions do not include that of providing legal counsel and representation to a library district.”
