Even if the rod of withering specifically states that it doesn't deal hp damage?
Tome and Blood defines weaponlike spells as spells that have an attack roll and deal damage.
This is not restricted to hit point damage - it includes hit point damage, subdual damage, ability damage (
not penalties), and negative levels.
Sneak Attack damage in the case of an attack that deals ability damage or negative levels is in the form of negative energy damage.
Monte Cook has stated that a sneak attack with a weapon that deals Vile damage (such as a Vile Lance) does
not deal Vile sneak attack damage, just normal sneak attack damage.
The Rod of Withering doesn't deal hit point damage, but it does "deal damage", per the definition of weaponlike spells.
