Fixed by adding brackets - etc...
dkim_domain = ${lookup mysql {select domain from admin WHERE
domain='${quote_mysql:${domain:$h_from:}}' limit 1}}
Whether this is correct or not - it works. I needed the domain of the
sender so I can provide the correct DKIM data. This was somewhat easier
before Tainted Data controls though in this case - all I'm looking for
is finding the correct DKIM records which only exist for Domains that I
manage... so is somewhat self-controlled already.

That would be quoting a string starting "domain:" and then
having the content of the From: header - which probably isn't
what you wanted.
Read the docs on string-expansions (and then worry if
the *header* data is what you should be starting from, too).
https://exim.org/exim-html-current/doc/html/spec_html/ch-string_expansions.html
This currently works: domain='${domain:$h_from:}' - but gives the
tainted search error ... but at least the DKIM part works.
If you really do want that source data, then you need two expansions:
an inner one to get the domain, and an outer one to do the quoting.
