I have a friend who did one of those super car track experience programs in a auto C7Z and they literally hosed the engine down every few laps because it kept hitting limp mode. He'd never even seen a track before, notwithstanding that PTM probably made it easy to roast the engine.

The automatics are going to run hotter, yes. The fact that you have more gears means the engine spends more time in the powerband and near redline, which makes it run hotter.
The ZL1's cooling isn't really more robust, but it has a much larger frontal area and more grilles to get more air into the heat exchangers. The Z06's grilles and vents aren't much different from a regular Stingray.
