So to start off One for all is a Enchantment that is meant to be used on late game weapons which the Livid Dagger is definitely not part off.
Next a Livid Dagger shines especially with its base 100 attack speed which makes any attack speed reforges on talismans unnecessary and allows for maximum syphon/life steal.
And in terms of what One for All would give you there isn't that much of a difference if you balance your stats properly and its generally a bad idea to put One for All on anything that has less than 300 Base weapon damage cause its just not gonna be worth it and you would gain more of upgrading your overall gear (especially talismans) with the money.
As for what i would do:
I would rather spend the money on getting more talismans, upgrade the livid in a different way (soul eater/swarm are good) or spare up for bigger investments like a yeti pet (in case you don't have one yet).
