Trying to find a Sonoma 14.1 installer... that specific dot version....

Hello... long story short, I have a corrupt/dead SSD drive that has only been seen as a drive by an M1 laptop running 14.1 in an Apple retail store. I have tried many many other Macs and PC's and other, later, versions of Sonoma, but that is the only instance where anything could see it as a drive. I could only try disk utility in the Apple Store as it was a store laptop with no third party options, and that was unable to repair it. So I am desperate to try and make a 14.1 boot drive but cannot find an installer. Can anyone recommend a direction for me? I have tried Mr Mac and Mist and talking to Apple. Thank you in advance, this is my first time posting on Reddit, lets make it spectacular. Ha.
