That's before factoring any magic resist, which Kog doesn't build to penetrate, but sure that sounds good. When would you build it though? That's one problem, another is that while his W is strong, relying on it over regular auto attack damage just means every other adc in the game would outtrade you easily, assuming a level 9 fight where he has a Runaans compared to another Adc that built AD, in most cases Kog is going to lose even harder than normal. I'm not one to just quote what pro players do as evidence, but I can say with complete certainty that they would know at this point if runaan's was actually a core item on Kog'maw. It may be good, but there's nothing I'd sacrifice over it except maybe a defensive item.

As for Kalista, her E is a huge burst of damage that resets if it kills something. With penetration and some AD, it's also much stronger against most targets than Kog'maws W. She won't melt a tank as fast as him, but with a runaans and her E reseting she can do similar damage, while also having much more mobility. It's also normally a second item anyway, following bork, so she has that going for her as well as some AD. The biggest difference is that it's a burst of damage though, we've all had that kalista do 1-2k Rend damage to us instantly for a kill, and it's much much more powerful than kog's w if you want to just compare damage.
