It simply TM pick different interpretation.

Yes, following real history, its impossible for Seimei to exorcist Tamamo as Tamamo case happened on 100 years after Seimei death.

TM ones most likely following popular beliefs that Seimei is half-human with high magical power who lived long enough to serve emperor from behind-the-scene; performing exorcist on Tamamo.

Many fictional works favor later ones-- mythical depiction of Seimei, as Seimei known to not experiencing any ill and possessing knowledge that is way above others (which is abnormal during that era), not to mention emperor's onmyouji division, where he works, is a restricted area that you won't find a single commoner lurking there during that time, contribute more to that beliefs.
