Because (define ...) will, AFAIU, define the variables in the whole
session, including subsequent code block calls. Let-binding is safer in
this regard - it only affects a specific code block.

For the problem of (import ...), a similar problem is solved by ob-C
using :includes header argument. See
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-C.html

I am not yet sure if let-binding around (import ...) must never be done
in Guile. It would be helpful of someone more familiar with Guile chimes
in.
