An interest in facts suggests to me, writing. Copywriting, blogging, industry news.
Being able to write with some expertise in a field of interest stikes me as something someone who wants to be home based, doing something interesting, but not who is otherwise not creative in an artistic way, could be.
Maybe look at Substack as a starter. Plenty of people, journalists etc are on it writing about all sorts of stuff. See if he might feel into writing about something which has the potential to get him into other writing opportunities. E.g. an area of interest that he can make professional connections within.
Also encourage him to use linkedin as a means to connecting with people who may be able to provide ideas for jobs.
Not just copywriting, but news writing is also increasingly being impacted by AI. Even mainstream newspaper publishers are advertising roles for 'AI assisted reporters' where journalists work with AI to produce content.
Newsquest is now employing seven AI-assisted reporters across the UK, up from only one as recently as June.

Additionally, while there are more wfh/hybrid roles in journalism since the pandemic, many of those who wfh are freelance journalists, and it's tricky to succeed to a level where someone can achieve financial independence - many have a partner who works in a more stable job, perhaps they come from more affluent backgrounds, have more resources, can rely on the bank of mum and dad, especially when starting out. Pay rates have stagnated over the past couple of decades, and also not just stagnated, some pay rates are lower now than they used to be.
As a result, lots of journalists have increasingly been diversifying and developing 'portfolio careers' because they didn't earn enough from journalism alone, so they also did copywriting, perhaps corporate or for charities/non-profits, and also PR and marketing. Some have commented recently how AI is already making inroads into copywriting. Those kinds of opportunities aren't quite drying up, but they're not as reliable a source of income as they used to be, seem to be fewer opportunities.
(Also, with the increase in HE, more young people going to university, there's more competition for journalism jobs in general, more graduates than opportunities available, so there are more journalists chasing the work, so demand-supply means publishers are in a buyer's market and there's downwards pressure on rates, as mentioned, and that's also impact by reduced advertising revenues online versus print, etc.)
Some people are making a little bit of money by publishing via Substack, mostly it's pocket money rather than a liveable income. Many use it as a means of publishing articles that they couldn't find a home for or to get something off their chest, for branding purposes. Some people are more financially successful on this platform, but they're relatively rare. It's better if someone has a niche, some expertise or a particular interest, to help build an audience. And obviously people need to be able to write in an engaging, informative, and entertaining way, which not everyone can do.
Thora Rather than output, like copywriting, blogging, reporting/journalism. It might be better to focus on input and working in the AI sector itself, rather than working in roles that use AI as a tool. That might be a way of future-proofing against AI taking a job, if their job is developing, creating, and improving those AI tools, instead of using them.
