I remember in the mid 2000s how some Xara Designer illustration software was able to do that, I don't know how isn't a more common thing (or maybe I don't know enough specialized software in that matter).
I remember well that program because it was available both for Windows and Linux, a really rare thing in that time.
Use tldraw. Steve rolled the perfect freehand library into tldraw and the tldraw implementation has been improved since then IIRC. So you can get the same experience and easily grab an SVG.

EDIT: However, I'm finding even with permissions a lot of these don't work to save to SVG...
Hmm I would need to fork it and fix it... maybe Inkscape is really the best option
