Did Dweomercore, Halaster's magic academy in Undermountain, exist in any published Forgotten Realms lore prior to Waterdeep: Dungeon of the Mad Mage? If so, where? Or was Dweomercore created for Waterdeep: Dungeon of the Mad Mage?

A web search doesn't turn up much, but here is one online post that states, "In older lore, I recall Trobriand actually set up Dweomercore..."

I could not find a reference in earlier lore

I found no reference in past editions to Dweomercore prior to Waterdeep: Dungeon of the Madmage contrary to what u/venkelos1 suggests in your linked reddit post. I checked the following sourcebooks:

AD&D 2e

  • Ruins of Undermountain
  • Ruins of Undermountain II: The Deep Levels
    (this book is where Trobriand was introduced)
  • Skullport
  • Undermountain: Maddgoth's Castle
  • Undermountain: Stardock
  • Undermountain: The Lost Level

D&D 3.xe

  • Expedition to Undermountain

D&D 4e

  • Halls of Undermountain
  • Undermountain: Halaster's Lost Apprentice

...and the following video games:

  • Descent to Undermountain
  • Neverwinter Nights: Hordes of the Underdark
  • Neverwinter Online: Module 16 and 17

All that being said, I may have overlooked a reference, or Dweomercore may have appeared in a source that I don't have access to, including one of the various novels whose stories involve Undermountain, or any of the "Dragon" magazine articles, a few of which certainly reference Undermountain (i.e. see the below quote from Skullport).

Some further information about Skullport appeared in DRAGON® magazine, and eventually the scanty information about it was brought together, slightly expanded, and updated in the City of Splendors boxed set.
