I think 2. is not necessary: minimal viable exterminator may be helped by some suicidal human beings or a sect. So it is likely to be a flu-virus-desings-generator, but the synthesis part will be made by a human.
Technically, in that case not all humans will be dead—but given vaccines failure rate and virus mutation rate, it will eventually kill everybody.
Also, vaccine-generating AI have to be more complex. Virus-generator could be just a generative AI trained on viruses code databased, which will also predict virulence and mortality of any new generated code.

Why would the human beings have to be suicidal, if they can also have the AI provide them with a vaccine?
