So far no one has offered the needed adapter to allow you to connect your SSD drive into. The only option is finding a second 2016/17 13” Fn MacBook Pro to slide your SSD into so you can recover the files.
As far as encryption unless you enabled it the drive won’t be encrypted. What I think has confused you is the newer 2018 onwards MacBook Pro’s which use the T2 chip by default have encryption. Sorry ;-{
