Will a pool sitting on the grass cause it to die and will splashing water on the grass kill it if it has chlorine in it?

Yes, an above ground pool sitting on the grass will eventually kill the grass. Most above ground pool manufacturers recommend that you remove the grass before filling the pool because the grass can also harm the liner over a long time. The actual chlorine in the pool water is unlikely to damage the grass on its own. More likely is that the water itself may damage depending on how much water gets splashed out; the exact type of grass; and how well the ground drains.

If sufficiently concentrated, yes. The amount of chlorine in drinking water, however, is not enough to harm your lawn. Even swimming pool water is usually not chlorinated enough to kill grass though normal splashing or draining.

Salt is actually good for your grass, but if you constantly backwash in the same place you could flood your grass overwatering it. And no, of course splashing saltwater will not kill your grass. Well, in my experience, our salt-water pool killed the grass around the pool - just from splashing. Also, the pool maintenance guys accidentally spilled pure salt on an area of grass and killed it. in fact nothing will grow back there now. We have just conveted to a non-salt water pool to see how well the grass rebounds. I wonder what effect the chlorine has on the grass at 3.0 ppm. BTW, there is only 12 inches of stone coping separating the pool and the grass. I'm curious where the first responder got his information.

I'm no expert, but if chlorine can kill you, then it can easily kill grass.
