I haven’t used it personally, but examining some in https://www.recraft.ai/community?imageParentType=vector_illustration https://www.recraft.ai/community?imageParentType=vector_illu..., I presume they’re producing raster images, and then auto-tracing. I looked at a few of the line-art samples they had there, and https://img.recraft.ai/--CWuHOOd2OaTTKRrIUsA-2nRJt-52M8NnXRtouGwSA/rs:fit:1024:1024:0/q:95/g:no/plain/abs://prod/images/28368b21-2b82-4125-ad18-dd1db2e60628@svg https://img.recraft.ai/--CWuHOOd2OaTTKRrIUsA-2nRJt-52M8NnXRt... has all kinds of artefacts that are just like autotracing tends to produce. For use on a plotter, the line art specifically needs to be a stroked path, rather than a filled path, and so for tracing you need centreline tracing, as discussed in the article. So you probably get absolutely no benefit from taking SVG—you’d need to turn them back into raster and trace them properly.
