Etymology: "Unbilled" is a simple formation: the prefix "un-", meaning "not", attached to "billed," the past participle of "bill." The prefix has been part of English since Old English, when it was used to negate adjectives and participles, and it descends from a Proto-Indo-European root for negation that also gave English words like "not" and "no." Its use with "billed" is therefore a plain negation of the earlier adjective, here meaning a thing that has not been invoiced or charged. "Billed" itself comes from "bill," in its sense of a written statement of money owed for goods or services, which is the everyday meaning that gives this word its sense of "not yet charged."
