Well someone needs to prompt the AI, find reddit articles to copy and make sure the final article has all the SEO to make it show up in searches to earn the company ad revenue. The high ups at Valent aren't going to do the dirty work and underpaying someone to be a writer also allows them to shift some of the blame should there be a major issue with an article.

The first sentence of Valent's about page says "Valnet was founded in 2012 by builders with […] an obsession with scale." Based on this I'm sure that at some point in their constant acquisition and gutting of known brands they will try or have tried having AI make and publish the articles directly, but I also feel like people are more likely to stop visiting a site where the content is directly from an LLM than one that has human written/edited articles with heavy LLM involvement.
