That's only because his skill nullify all that try to read his power. If anti-psychic/magic can be read and label, the boy would probably be a level infinity.

In the novel, level 0 is practically cannot be measured or practically no ability, in Touma's case is the first, and for that ability he has been cataloged as a Jewel (or something like that). There are some characters in that category, Sogita_Gunha, who practically manipulates the Air Pressure, at will.
Regardless of technicalities, it's pretty cruel and insensitive for Saten, who dreams of a power of any sort and feels inferior hanging around with her esper friends, to be groupped together with Touma as a Level 0. After all, Touma's immeasurable power was enough to beat the former number 1, Accelerator. And repeatedly stand against Biribiri as well. Misaka just happens to be Saten's idol as well.
