Having read your anaylisis, and then some, and looking at part from the books and the movies. I find one problem with the lysine situation. Though the park might have readily supply of cows, chickens, and other game. They would have been cooped up in an enclosure that required limited access to the public, well secured, and controled (as demonstrated in the Rexy's paddock scene) ran on electricity. When the power went our I can beat no one was concerned about letting a bunch of farm animals out, so the poor beast would have been trapped and died in their areas.

And from the gentic pool (Not counting Jurassic park 2 or three) there were no names listing the fish eating dinosaurs, and while there are herbivores they as stated recieve their lysine from the handlers who gave them the food they required (not planted randomly in their enclosures to feed off), so what they had was ticking amount of time until the lysine was depleted from their bodies. As noted by Elen Satler who evaluated that the plants they brought back could or could not support the plant eaters, with the side effect like the trike being poisened by the barries

If that is the case the herbivores food supplu would have been quickly isolated and devoured withing a month. The lysine they depened upon would eventually run out, "go into a coma, and die". Rexy would been spared that horrible fate until every prey that had lysine was either eaten or rotten. Thus those that remain would yelded nothing for her to feed off of, which would eventually lead to her own demise

The best way this problem would have been answered would be through the game, which shows the antidote being put into the water supply curing not just Rexy, but any dinosaur that drank from the river. In this way if any of Rexy's food supply survived after the ground zero effect then she could feed off a continus resource

That is my two cents
