To my knowledge IBM doesn't supply or support these utilities in this way, 
but you can always ask (RFE: https://www.ibm.com/developerworks/rfe ).

That said, if you're willing to go "off label" (but within license), Dave 
Gibney makes a good suggestion: see if Jan Jaeger's ZZSA offers some 
inspiration. Another "wild idea" that comes to mind is that Linux has 
offered "raw-track access mode" for quite some time, and conceivably you 
could use that. Specifically, it may be possible to create IPL'able 
instances on DASD (ECKD FICON-attached storage) of the particular 
stand-alone tools you're interested in, use a DVD/USB-booted Linux 
instance to back up the whole volume (to something network-attached, for 
example), then reverse the process but with the backed up volume available 
on the DVD/USB flash drive itself. Then as long as you have some sort of 
ECKD storage available you should be able to "bootstrap" the particular 
stand-alone utilities you want to run. I haven't tried this, but it seems 
technically viable and not too far "off label."

A variation on what I just described substitutes tape or virtual tape for 
the ECKD storage, as long as the Linux "bootstrap" instance understands 
how to read/write to/from such a device. This would apply to stand-alone 
utilities available in tape IPLable form. (ZZSA can also IPL from 
tape/virtual tape, so it's a reasonable test candidate if/when you're 
trying to build a Linux "bootstrap" image.)

z/VM and z/VSE supply their own DVD/USB IPL'able "bootstrap" images, so if 
you're licensed for either or both of those products they might offer 
something useful.

I should also mention that you don't necessarily need physical access to 
the HMC/HMA. With authorized remote HMC/HMA access you can upload an 
IPLable .iso image (with .ins) to the HMC/HMA and IPL a partition from 
that. And/or instruct the HMC/HMA to IPL from a network reachable 
.iso/.ins.
