Steven, so a redirect from Unknown to a sourced LNAB is good; but, a redirect to correct a spelling error is not so OK? Is it worth the redirect?
Let me repeat and emphasize my previous comment:
"This issue is primarily with multiple redirects in the same profile..."
That comment was meant strictly as a guideline and not a blanket statement about not making redirects (when appropriate).
Corrections are always good for the tree. We just need to be cognizant of the history of the profile, the current state of the profile, and what the future changes to the profile might look like. We have to remember that every change made on a wiki has a "cost".
In the case of this specific profile, Unkown-1098, I would say the change to LNAB is fine to make, since "Unknown" may unfortunately be her legacy here on WikiTree.
History: No merges and/or LNAB changes to date (meaning no existing redirects).
Current State: Correct (sourced) LNAB will be difficult to find, and many people have apparently already tried.
Future: LNAB may never be found.
Based on the above, we only talking about one redirect now, and if we are lucky, a second redirect in the distant future to a correct (sourced) LNAB. This small number of redirects poses no issues.
