Yes, the lady on YS387 has Ritual (Crafting). She's chosen a functional limitation on her Thaumaturgy, like Ritual (Summoning) or Ritual (Veils). She's also missing two enchanted item slots, but whatever.
Using a thematic limitation will still allow you to craft (if crafting were a thing that happened anywhere but off-screen or as fluff). This is noted right at the start of the "Thematic Thaumaturgy".
"All the types of thaumaturgy listed so far are divided along functional lines. Plenty of spellcasters focus their specializations by function—you have divinators, wardsmen, crafters, summoners, and the like. But just as often, thaumaturgists specialize not along functional lines, but instead along thematic lines. A thematic specialization looks at the subject matter in which all the various functions of thaumaturgy are applied—an ectomancer will be particularly effective with summoning, binding, divining, veiling, warding, crafting, transforming, disrupting, and transporting ghosts and other non-demonic spirits, for example."
Diabolism refers to spellcraft that uses a demonic component. Therefore, my craft involves using demonic ichor to etch out runes, heating metal in hellfire, binding minor demons inside the fabric of an object, and using ancient infernal recipes bargained away from bound devils to create potions. I'm going to be stinking of demons, which should lead to decent compels, and I can still craft for pretty much any suitably demonic effect I want... While also being able to summon demons or place demonic curses or set up wards against demons or the holy.
RAW, you don't need any other spellcasting abilities to make an enchanted item, thanks to everything happening off-screen and thaumaturgy not being actually necessary.
I'm going to see what the GM says, anyway. This isn't even for my character; it's for someone who wants to play a twitchy, drug-blasted alchemist. I'm going to be playing a demonologist spirit eater (Ritual: Diabolism with the Mimic Abilities power - bind 'em and chow down, cue the crazy).
