I was able to use EaseUS to restore what looks like the content of the drive
Ah ok. I thought you just restored the MBR to show the partition. You meant a file recovery to a second drive.

If that's the case, the drive is not encrypted. You wouldn't have been able to pull off any data if it was.

Hard lesson to learn, but that's why you always have multiple copies of important files. Even if you pay for the service, there is no guarantee they will recover/restore all the files.
