I dought very much that a creature the size of a khezu could lay eggs in a creature of that size and speed.

There is however a solution, one used by real life bot flies. The fly larve need to be in an animal (cow, horse, human, the list goes on) to grow by eating it. But the fly itself is too large to land unoticed on an animal. What they do is catch a smaller fly, lay the eggs on it, and let it go. The small fly lands on the animal, the eggs hatch due to detected body heat, and burrow into the fleash, where they proceed to eat thier host alive.

I think khezu could do a similar thing. But maybe make the animal eat a carcass with eggs in it. Or something like that.
