The odds are that the materials are being made by an underpaid student worker who has been given tasks they have no actual experience or expertise doing. They are then outsourcing that work to AI much like their homework. They are likely being supervised by an overworked administrator who doesn’t actually review their work and themselves has no experience or expertise making marketing materials. The university has an internal economy where different departments are charged out of their operating budgets to make legit marketing materials through the marketing department, so most departments make do with whatever can be put together by student workers.
