re: Harder to Graduate from in 4 years... LSU or Harvard?

Depends on the major, but for most it is the same or easier at Harvard. As others mentioned it is about getting in that is hard. Once there, it is no different from most any college when it comes to course load and in fact grading is likely easier because “we are taking the best kids, of course they are all going to get A’s”.

That said, LSU has also become a joke in many ways and it is way easier to get good grades now than before because they pander to the students AND many faculty don’t give a crap about teaching. It’s just an obligation to them, and easier grades means less students “needing” help.
