In terms of ChatGPT, I think yes if you ask a specific 'deepresearch' module then it could probably compile that in about a minute.
I took a look at my Milbank application, which i felt was incredibly generic but made it through:
Why us?
1. explain my international background and how it's relevant to an int'l firm
2. check on Google that they do Sharia finance. Explain my interest. (Reusable point)
3. points from legalcheek/chambers student about their training process, relate to myself: again generic in that other firms will have similar processes
(didn't even mention specific deals or lawyers, so could definitely have gone a lot better)

I gave some bullet points about AI legal issues including copyright, GDPR, DMA, etc. and related it to investment in AI. This was an answer I repeated to several firms but spending ten minutes perhaps relating it to my understanding of the firm in question.
OTOH I do have non-legal work experience, but the work experience definitely isn't sufficient to get you through - you do need to write relevant, literate answers - I did some even lazier, more terrible answers last year, and it was hopeless - nothing can outweigh a 150-word answer to a 300-word question or whatever
I wouldn't necessarily counsel people to follow my approach in terms of not giving ultra-researched answers, because it might not work for you, depending on what the rest of your application form looks like, but I can say that the more applications you do, the more you will acquire reusable answers to the behavioural type questions, so it definitely makes the process easier.
