Milk that is soured by human addition is no more alive than the source of the milk and souring agent.
If uncontaminated lemon juice or vinegar is used, the "sour milk" will not contain micro-organisms.
Milk left out at room temperature to sour, does so because of the micro-organisms in the air that land on it and then begin to use the milk for food. Most produce mild acids in this process which is why natural sour milk does have live organisms.

No, unless you leave it out in the open in a shallow bowl.
