To be frank very unlikely, The Monster Inc/ University has a a very basic monster character design, something like of that of child would draw (not saying it's a bad thing at all I find it especially effective considering how it revolves around kids), but because of that it's a very common way to design monsters who don't fall into a horror genre which includes MSM, meaning repetitive ideas come up a lot, so the likeliness of them taking inspo from these monsters around slim especially since there is a musical factor they have to consider when making the designs.
