Technically, none of the creatures in ALL Jurassic Park movies have "real" dinosaurs in the story.
As explained in Jurassic World (and Jurassic Park as well, if my memory is correct)... Their "dinosaurs" aren't necessary perfect dinosaur clones, but rather have other DNA mixed into them to make what we think are dinosaurs, but not necessary are them ever...
So really, the main villain of Jurassic World isn't a dinosaur simply because the rest are NOT either. However, if you don't nitpick that much then you should totally count the main villain as a dinosaur, simply because (just like the rest), they've used DNA from the original dinosaurs (that are long dead). Specifically Raptor and T-Rex DNA (and obviously mixed in with a lot of other animals of today to fill in the missing pieces).
As for the rest of your post...
1. It doesn't need to be backed by a book in order to have an interesting and great story, with memorable characters and all. A movie can be just that on it's own and, in my opinion, this movie does just that while still giving the original Jurassic Park idea some good justice (yet at the same time, it's still it's own story with all of it's own characters and development).
2. Like I said above, they aren't technically dinosaurs... Just new creatures made to be like 'reptilian dinosaurs' (you may say).
3. Again, what I said above about the second part. As for the former part, generic monster movie? Eh. A little. I wouldn't say the movie as a whole is generic, though the main plot itself (the one around this main villain) does share the basics of a 'generic monster movie' but it still has a lot of it's personal taste to make it not like that but instead a great movie on it's own.
