While I can't find anything that narrows down Lea Monde's location beyond Greylic's Bend/Golmore Jungle region, we can at least scratch that Valnain isn't the country. It is described as a port city.

Encyclopedia Eorzea II: "The mention of Dalmasca conjures images of a kingdom rising from the desert, but at the edge of the sands lies the port city of Valnain, known for its history as a center for shipping. In the Valnard Sea to the south, a lighthouse perches on the lip of the Ridorana Cataract - a gaping maw in the ocean believed to lead into the seventh hell. This spire illuminates the path to the northern sea routes, and thence to the docks of Valnain. With advances in Gyr Abanian navigation techniques, overland caravans slowly gave way to merchant ships, but Dalmasca’s hold on the shipping lanes ensured its continued prosperity.”
