Etymology: "Unfoundedness" is a plain formation: the adjective "unfounded," meaning without foundation or basis, with the suffix "-ness" added to turn it into a noun naming the quality or state. "Unfounded" itself is built from "un-," a prefix meaning "not," attached to "founded," the past participle of "found," in the sense of establishing something on a base. The image is literal: a claim with no ground beneath it, like a building without a foundation. "-ness" is one of English's oldest and most productive noun-forming suffixes, descended from Old English and attached freely to adjectives. That productivity explains why it can be added to nearly any adjective, including ones like "unfounded" that already carry a prefix. The result names the abstract condition of lacking support rather than the unsupported claim itself.
