Is this the same as Iola LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — City of Iola - (KS) here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Iola LLC" usually means this site.
