The upcoming release of Thulia Ghuld, Archmagos Terminus of Mars who "is a veteran of the Ordo Reductor" got me thinking - Is the Auxilia Myrmidon part of the Ordo Reductor?

I've got it in my head that they are, but I'm not sure where that idea came from. Looking at Lexicanum there's a reference that Myrmidon Destructors "are dedicated to the Ordo Reductor", but that's from the 30K novel Wolfsbane. Are there any other references?

Probably. They really like guns; the Ordo Reductor also really likes guns.

In Betrayal, Calleb Decima's Ordo Reductor list told you to use Myrmidon Destructors (using techmarines as stand-ins, since Myrmidons had not been released yet at the time). They are explicitly called Reductor Myrmidons, so make of that what you will.

With that said, it seems this is a matter of delegation. Massacre explains that the Myrmidons form their own independent sub-cults within the larger order.
