Reiatsu is a personal force exuded by the individual's reiryoku, which is an energy aligned to their will. Kido is created by essentially using reiryoku to put together something out of reishi. In an easier way of understanding that, it's like energy expended to either form bonds or break bonds in Chemistry. And the nature of those reishi bonds and the effects the resulting structure takes is dependent upon the caster's degree of skill and power. Kido is not solely reiryoku; it can be, but you'd tire out way too quickly trying to pull off multiple spells using just your own reserves. But that's neither here nor there, since a spell does not have a will of its own normally. It can, of course, but that is a skill that only the most elite of the Kido Corps would have; like, hardcore Kido specialists. So, bottom line, it does not exert reiatsu.
