I ended up resolving this problem myself, but wanted to provide some documentation in case others run into this problem.
The biggest issue holding back the model is that the Make Query Table tool would not accept the existing CondoTable as a valid input (not sure why since it was the default LGIM-enabled database). I modified the model with a copy rows tool to export the table to the output GDB and used the new condo table as the input. This allowed the inputs to the Make Query Table tool to be accepted. All the field names and expressions had to be corrected.
Additionally, most of the field names for the other geoprocessing tools were incorrect. The model was not updating to match up with existing fields. I went through step-by-step and corrected each tool to match my schema.
Finally, I updated the model to have the user simply identify an output workspace. From there the model builds a GDB and an appropriate feature class inside.
ESRI has pushed all support for Parcel Fabric to ArcGIS Pro. While I understand this is an obvious choice, I know that some users will still be stuck in Desktop for some time. Hopefully someone finds this helpful.
