From what I've experienced, deathfire touch only procs from abilities and not passives. So for example Teemos E will not proc it, but Brands passive will proc it because his passive is triggered by his abilities, whereas Teemo cannot cast his E. It does not proc on damaging summoner spells (aka ignite), but damaging toggles like Singed Q will proc it. I'm not sure how it would interact with Aatrox toggle since that has a damage/no damage component and is passive.

tl;dr: No. Interestingly, his Q does not apply it either, most likely because Parrrley is in many cases treated like a melee attack, meaning he would only benefit on E and R, E with reduced effectiveness and R with reduced effectiveness depending on how long they remain in the area.
