I don’t think a single hitch would give the AI enough evidence to assume an entire other universe, and you may be anthropomorphising, but why argue when we can avoid the cause to begin with. Its fairly easy to avoid cosmic rays or anything similar interfering. Simply compute each cell twice (or n times) and halt if the results do not agree. Drive N up as much as necessary to make it sufficiently unlikely that something like this could happen.
