LPI was pretty much non-existent when the F-117 was designed anyway.
Remember that this was essentially a late 1970s design, with the first
planes delivered in the very early 1980s.

I think a couple of other posts have made the same comment. It is my
understanding that the Tacit Blue program used LPI before the F-117 was
built. Is this incorrect?

Not really: the F-117 first flew in June of '81 and Tacit Blue the following
February. Recall also that the F-117 was a developed/operational version
of the earlier Have Blue concept plane.
