I did consider that it wasn't available in THF and perhaps part of ROF2 client, but the text says:
"You must use the solvent Lillu's Magical Distiller, or a Perfected Augmentation Distiller, to remove this augment safely."
I decided if the text had been customised to add Lillu's distiller then it could have also had the Perfected one removed, so it's possible it is available.
The text came with ROF2 so it's possible the line is there just from the client and there's just other code in the background that says to add the Lillu to aug discription. But i've been wondering, so it couldnt hurt to ask

Edit - what's offered by the haggle baron? One of Lillu's distillers? I do have the bird bath on my main tank but i'd like to aug up my other 2 tanks with the ease of being able to transfer those augs on upgrading gear without having to buy the same donor item 3 times.
