Turning off CSS can be useful to determine the content order of the
page, the order which a screen reader user sees
If CSS is used to rearrange content visually in a way that changes its
meaning (e.g. createing a table like layout with CSS butnot using
table semantics) it is an accessibility issue that could be detected
this way. I've seen examples of this, but they are not frequent and
could be picked up through use of a screen reader.
Turning of cSS also helps identifying CSS icons or images, they
disappear while HTML and SVG images stay. If CSS icons are meaningful
they need a text alternative.
Paul Adam has a pretty good image and alt text bookmark that can e
used t detect CS images and also whether they get their text
alternative from role="Img and aria-label="the alt text".

The downside of turning off CSS is that you may see and even test
content that Is never meant to become visible to any user, such as web
analytics.
