T. rex had a bad grip that Spino wiggled out of by thrashing about.
It's never established that T. rex has a huge bite force in these films.
In fact, it's SHOWN that the T. rex can't even kill a Gallimimus, a Velociraptor, or even a human in one bite. Even if you wanted to get paleoautistic about it, there's evidence of dinosaurs surviving T. rex bites, so you can't hide behind non-criticisms of it being "inaccurate."
They're just giant frog monster cooked up in a lab to be whatever the script needs them to be, killing each other over a territorial dispute at the end of the day.
It's time to get over it, anon. It's been 24 years.
