Yes, some people do strive to brew purposely infected beers- Berliner Weisse, Flanders Red, Lambics, Gueze, etc. This can be accomplished by pitching a commercial strain that contains the necessary bugs or, in the case of Berliner Weisse, employing a sour mash.
In reviewing the directions that you linked to, it seems that you did everything correctly with this 'no boil' kit. The malt extract syrup is prehopped and already pasteurized. If you have a lacto infection, your tastebuds will be your best indicator. Lacto is very tart and sour, almost mouth-puckering so. Have you tasted it?
