Both Raise Dead and Revivify deals with existing dead body. And providing that tadpole technically is a part of your body at that point - it gets revived as well.
The only way truly get rid of tadpole is to use resurrection, true resurrection or reincarnate. (or Clone, for arcane spellscasters)
Well, or major restoration that is... obviously all those options not available for low level party.
