If you care about the person and want to talk with them, reach out and be genuine. If not, don't bother them with LLM corporate-speak masquerading as support. Let's be honest: they didn't "part ways" with the company--they were fired.
Right now, they're worried about paying their bills, not about making their former coworkers feel better.
If you really want to help, reach out to your network and see if anyone is hiring. I've successfully connected many laid-off former coworkers with new opportunities. I've even approached recruiters that I ignored saying, "I'm not available, but this person is looking, and they're excellent."
I can think of few more grotesquely slimy developments in the last century or so of human communications than the blandly saccharine corporate-speak that now prevails in government and business like an ever-spreading parasitic infection. It permeates nearly everything and is used as a shield by shitbag executives and grossly corrupt organizations to disguise their true nature and the many examples of mendacity that their activities really involve.
Now we also see it being applied by the actual people, real people, communicating informally with real other people inside these same organizations, even when they apparently mean well in their own brainwashed, dimwitted way.
If I ever had anyone write a goodbye message to me in which they described me getting my ass fired as "parting ways", i'd plainly tell them to shove such nonsense wording up their ass if they really give a shit about me, or about being human.
