There's still something that's confusing me. Immediately prior to the
sentence you quote (5-4-7b), the AIM says "for aircraft operating on
unpublished routes or while being radar vectored, ATC will, except when
conducting a radar approach, issue an IFR approach clearance only after
the
aircraft is established on a segment of a published route or IAP, or
assign
an altitude to maintain until the aircraft is established on a segment of
a
published route or instrument approach procedure".

If you're being radar vectored and you're then issued an IFR approach
clearance, doesn't that constitute a radar approach? If so, what does it
mean in that situation to say "except when conducting a radar approach"?

Regarding radar approach - no, radar vectors do not constitute a 'radar
approach'. The term 'radar approach' refers to approaches using ASR and
PAR. It's in the AIM but don't have the reference.
