The bondholders paying or entitled to receive the benefits of such bonds shall have a lien on all such funds until applied as provided for in any resolution or trust indenture of the authority, provided that revenue bonds issued for the use and benefit of a person, firm, corporation, limited liability company, or other type of private entity shall be a limited obligation of the authority and in the event of default, the remedies of the bondholders shall be limited to the funds identified in the resolution or trust indenture and not the funds held by the authority as trust funds or otherwise.
