Who is Russians and the KGB from The Man with the Golden Gun and what is their importance?

Russians as a group are portrayed in this book as the puppet masters, the behind-the-scenes manipulators of the international war/drug/gambling/espionage rings confronted by Bond throughout the book.

The KGB was the shorthand name of the Russian Secret Service, responsible in life as in fiction for international espionage and national security. They were, in the eyes of the west, the agents of Russian evil around the world.
