I think the key thing is the free text (like the current free text) doesn't actually do anything of any significance
Sure, it's megalolz when you add "and journalists are cockroaches and scum, and I'm sleeping with the chairperson's daughter" and you get an AI write an article about it, and the article is quite coherent and believable even though it does also accuse you of being a racist. Then you still have your job and journalists still like you, and it's not exactly adding to the realism.

Similarly, the assistant's advice is unreliable enough already, a glorified text continuation engine that's absorbed lots of sentences about FM and football but has no idea how to actually play the game and needs careful prompt engineering to generate any advice at all isn't an improvement (seriously, if you type out which striker is better in every relevant attribute, it's not a surprise a text continuation engine could give you something that looks like a reasoned answer based on which attributes one striker is better than the other. Yago Cariello is a crap Complete Forward and Rochez probably better suited for a pressing and counter attacking game though, so I'm not sure it's a good answer except from the point of view of being coherent text...).
Every time it gives you a good answer like suggesting that although Messi is a world class footballer he is not typically considered a good target man [because he is not known for his strength or aerial ability), it'll give you a bad one like suggesting he's an excellent pressing forward. The game already has functionality that's a bit like that sometimes, but at least it can be debugged...
