In the 90s it was common to see licence text refer to "the regents" even when that made no sense, but that's faded away as actual template licence text, meant to be used as a template, has become readily available.

I don't think it affected the interpretation much. If the author and the regents disclaim the warranty, and there are no regents, the straightforward interpretation is that the author disclaims warranty.

"The Regents" was likely an artifact of advertising clause, not of people being lazy filling in placeholders in the license.

(I believe quite a few bits of Windows will still, thanks to advertising clause, remind you about the Regents of the University of California)
