You must still learn how to program. LLMs do not actually know or understand anything, and so they insert mistakes all the time. To ensure the code is good, you have to review it, and you can't review it if you don't understand it. If you don't learn how to program, you're going to be setting yourself up for a world of hurt when the LLM starts doing a bunch of stupid stuff but you don't know enough to catch it.

Also, you didn't ask but: be careful about going into tech. 5-10 years in the future is probably far enough that we will be able to see how the AI craze impacts jobs, but right now it's a very uncertain career which is at risk of going away because the business people think they can just have AI do everything. They can't, and they will learn that the hard way, but that will be cold comfort if you're out of work in the meantime. So be careful about choosing this field, it's hard to know what the career potential is like right now.
