I dealt with this exact problem during my own kitchen setup last year - I was hoping to avoid calling someone out but learned pretty quick that it's not as straightforward as swapping outlets. The issue is that USB outlets need their own dedicated wiring setup inside the outlet box to actually work safely and deliver proper power, so you can't just pop one into an existing standard outlet slot without some wall work or replacing the whole box. Honestly your easiest move is grabbing a few USB adapter plugs for your existing outlets - they're cheap, work fine, and zero wall damage. If you really want hardwired USB outlets later, that's when you'd need to bring in someone, but for now the adapters do the job.
