Export the page in question to a raster image format like PNG at a high resolution, use an erasing tool on it, re-import the whole thing as a high-res raster (not OCR).

In the past 15 years I have seen so many poorly redacted PDF from government agencies, where they just draw a black box over the PDF-native text.

And then ORC afterwards for acceasability. Muller has not messed this up yet sadly.
