Disk Drill 3 is now capable of creating your own bootable Mac OS X USB drives for data recovery.

How to create macOS Mojave USB installer with Disk Drill
To create a bootable Mac drive you need any disk with Mac OS X 10.11.0 El Capitan or newer (10.12 Sierra, 10.13 High Sierra, 10.14 Mojave, 10.15 Catalina) either running as your main system, or just being installed on a drive that's connected to your Mac at the moment. Go to "Create Boot Drive" feature, and choose the drive you would like to copy the OS X system files from to the new drive that we are building. Once the source disk is selected, proceed with choosing the destination to make a USB bootable drive.
Disk Drill's data recovery boot disk is also an ideal solution when systems with deleted data that needs to be recovered fail to boot from the internal drive. Once your Mac USB bootable drive is created, you are ready for data recovery at any time.
Make sure you try all available data recovery methods to get your deleted data back. Also note: Disk Drill does provide a separate feature to install a new instance of Mac OS X using the bootable drive that can be created with it. However, this article explains the steps required to create the Mac OS X USB boot disk for lost data retrieval and running Disk Drill in a ready-to-use standalone recovery environment.
Disk Drill for Mac can create byte-to-byte disk and partition backups, allowing you to recover even from the most catastrophic data loss situations without losing valuable files, settings, and other data.

I booted that and got the same A software update is required to use this startup disk error in recovery. I tried to reset the mac to its original OS after that with Shift+Option+Command+R, but after loading with a rotating earth for a few minutes I get an exclamation mark sign over that earth with the following below it:
