Why is it so unrealistic? For example, this line in Mumbai metro ( https://en.m.wikipedia.org/wiki/Line_3_(Mumbai_Metro) ), with 34 km of big tunnels and 27 stations is supposed to cost 3.4 billion. Surely, Chicago's 25-30 km line with just two stations (one sort of half built already) and smaller tunnels won't cost so much.

Two things. 1 is that they're planning to use a lot of cut and cover which is a lot cheaper but more disruptive. 2 is that the project isn't complete yet so those final cost figures are still fiction.

No, only the stations are cut and cover. They have ordered 17 tbm for the tunnels.
About the cost estimate, I don't have any other completely underground metro line in a developing country to compare. But Is it the labor costs in developed countries?
