In what manner would you expect pilots to rely on the note "ADF REQUIRED" on
the SAC ILS or LOC RWY 2? When ADF is actually required on non-NDB
approaches the note "ADF REQUIRED" adds nothing to the approach, it simply
states a fact. When the note appears on an approach that can be flown
without ADF it only creates confusion.

.... in the same manner that pilots would deal with being given a
clearance to fly an ILS when they did not have an ILS receiver aboard.
I expect pilots to rely on the publication as accurately reflecting
facts, and the presence of "ADF Required" (which as stated upthread was
actually initiated by NOTAM) would be relied upon as reflecting the fact
that ADF is required.

I would not expect pilots to second-guess NOTAMS or approach procedures.
If it says ADF required, then an ADF is required.

So, if cleared for the approach, and no ADF is aboard, the word "unable"
or some equivalent would be legally required.

As you note, when the note is "in error", confusion results.
