This reminds of when Adam Wathan admitted that LLMs really helped his workflow due to automating the process for turning SVG's into react components... something that can be handled with a single script rather than calling an LLM every time like you mentioned.
Sometimes people just don't know better.
That depends on the content of the SVGs.. Of course you can write a script to do a very literally kind of conversion of regardless, but in practice a lot of interpretation would be required, and could be done by an LLM. Simple case is an SVG that's a static presentation of a button; the intended React component could handle hover and click states and change the cursor appropriately and set aria label etc. For anything but trivial cases a script isn't going to get you far.
