"gdalinfo --format GTtiff" will report the options available in your

In the brew formula. In the libtiff one more exactly, as this capability 
comes from libtiff. Just checking 
https://github.com/Homebrew/homebrew-core/blob/b4698a581c0d752241353682fecd627d85ca6dd6/Formula/lib/libtiff.rb, 
it lacks a liblerc dependency.

You could try from Conda, since its libtiff includes lerc support (3.8.1 
hasn't yet landed there, but it should come soon)
