I'd say if you're looking to study mathematics or computer science at university, they generally would like (and/or expect) you to have taken further maths if you have the option to take it alongside mathematics.
I also looked at for example Oxford's A-level subject requirements if you want to study their Computer Science BSc and it doesn't mention a need for taking A-level Computer Science.
Therefore, rogue take but could be helpful, have you considered ditching A-level Computer Science altogether?
While I can see that it would definitely be useful to get an A-level in Computer Science if this is your intended career path, in my experience of being in University for 5+ years, I have seen that most of first year content is just a revision of the full A-level syllabus. Therefore, should you study a Computer Science degree, you are likely to be taught most of the A-level content within the first semester of year one at university. So yes, you could take a computer science A-level, but it could leave you bored at the start of the year at university while you could have used that A-level choice for a different option.
I would say, if you are interested in a career in AI, you might change your mind after a few years. However, if you're interested in that, it suggests you are interested in applied mathematics in some way.
Have you thought about the combinations: Maths, Further Maths, Physics, EPQ? Maths, Further Maths, English Lit, Physics or any combination like that which does not involve Comp Sci? Could even take Chemistry instead of Physics or English Lit as it would be an even broader field with even more options and taking Maths, Further Maths and Physics together could be tough (Although completely doable if you don't mind working hard! Nothing good is every easy!)
The reason I haven't necessarily suggested taking out English Lit is because A-levels are hard and you want a subject that you enjoy and could take your mind off hard subjects every now and then too! Take my advice with a pinch of salt though. I am not a university adviser, but from personal experience I'd say that it is nice to have a subject in there that might be a bit easier to you and that you really really enjoy, which I assume is your reason to put English Lit alongside STEM heavy subjects
