comment Why do so many identities for the Logarithmic Integral begin with the terms $\log \log n + \gamma +…$?
Every identity you have stated involves $\text{li}(x)$, so there really aren't "many" identities involving $\log \log n+\gamma$. What is really happening is that you have just stated several identities for $\text{li}(x)-\log \log x-\gamma$, and it's not really surprising that we can write this in several different ways. The question that seems to be more natural is "why does $\log \log n+\gamma$ appear when looking at $\text{li}(n)$?"

comment If a series diverges, dividing it by the sequence of partial sums preserves divergence
@Umberto: The question states that the $x_i$ are positive, so no $s_n$ cannot be oscillating.
