It's been a long time since I last played the game but I don't believe that's true without cheating.

There's only one situation that requires tricking the AI to open a door for you (what some might legitimately consider an exploit).
Other than that (which I consider a design flaw) it's entirely possible to get by without killing anyone (though using non-lethal weapons to render people unconscious is of course still necessary at various times).
