I wouldn't be surprised to hear that this was always the plan for Kagi. Google has been rather distracted and complacent in their, former, core business. If Kagi is bootstrapping their indexing to emerge on the other end of this as the next "good" search, then good on them.
I'll continue to support them because it's a great experience.
I like paying to invest in a new sustainable ecosystem. Using SERP API doesn't feel like that to me. See Brave for a counterexample.
It is a bit weird that a ‘search engine’ is using other companies search results. They aren’t the only one doing this though.

Why reindex everything? You just need to show the relevant information
If engine A uses the results of engine B, and engine B uses the results of engine A, there is a problem :-).
