Technically no, because it's a weird "not-quite-an-attack-but-simulates-an-attack" troop thing. But the flavour is definitely the enemy hitting you, so I'll say that it counts.
BUT.
Dutiful Strike says Trigger An enemy within 15 feet of you hits you with a Strike and deals damage to you.
I believe you weren't within 15 foot range at the time of the attack. You've moved since then, but if I read my version history right, Aesephna was 10 feet away from the troop and you even more, so a) you weren't in 15 feet for the trigger, and b) she wouldn't have the reach to hit it anyway.
If you move to within 15 feet (which you've done with your current turn, I see), yes, you can do Dutiful Strike.
Good catch, the reaction is weird as:
Enemy need to be 15 ft from Dorianna - they were further away so no way Jose!Eidolon needs to be 15 ft from Dorianna - that was true
Eidolon does not need to have reach to the enemy per the description of the feat: ' Your eidolon makes a melee unarmed Strike against the triggering enemy, even if that enemy isn't within your eidolon's reach.'
So in theory Eidolon can swing a hook 30 ft away (15 ft to enemy 15 ft to eidolon)
Herp derp, good catch.
