I am trying to make use of a project that is no longer maintained that relies on pdflatex. However,
% brew install pdflatex

Warning: No available formula with the name "pdflatex". Did you mean pdf2htmlex?
==> Searching for similarly named formulae and casks...
==> Formulae
pdf2htmlex
To install pdf2htmlex, run:
brew install pdf2htmlex
% brew install pdf2htmlex
Error: pdf2htmlex has been disabled because it has an archived upstream repository!
Is there a dropin replacement for pdflatex that I could use to get this program that depends on it to run?
pdflatexis very much alive and well, but rarely (if ever) packaged by itself. You want a TeX distribution which will provide it instead. MacTeX fits the bill and is available through brew.
