KataGo just showed me this (one of several equally good options). Of course

could be at either a or b instead.

Either a or b next, and then lots of choices...

I'm not so surprised. In this position I'd expect a and b to be good local moves, but maybe c is usually similar to any other good move on the outside, for example d. c feels like kikashi to me.

The marked stone means that black is about to connect and make territory but without this stone there is a basic joseki here. This joseki has many opportunities to pick fights and go for something unusual and I wouldn't expect KataGo not to. In any case, c would often be "the Only Move"-tm here.
