Truth seeker orbs do not have existence eraser.
Here hiruzen says it merely turns things to
dust. Granted this was before the yin-yang release was added. However yin yang release does not give it eraser properties. It just allows him to nullify
ninjustu. I understand tobirama stated it erases things. But this is contradicted many times on panel
Here madara's tso hits the ground and creates
dust and
fragmentation.
Obitos tso showing
vaporization. Obito's staff on the ground yet the ground is not
erased
Naruto's tso pulled to the ground in Kaguya's gravity dimension. Yet the ground is not
erased. Also
here.
So that being said there has not been a single time where tso has erased something. Every time it's either nothing happening or vaporization when it comes into contact with something. Which is consistent with Hiruzen saying it turns things to dust.
Before someone says they can turn it on and off there have been many times where the user had killing intent yet we still don't see vaporization. This ability should also be passive considering it has all naruto types in it. If tso was EE the ground would be erased and no smoke would show.
