Sep 6, 2021 at 20:46 comment added GH from MO @JoséHdz.Stgo. The RH implies $|\pi(x)-\mathrm{li}(x)|<\frac{1}{8\pi}\sqrt{x}\log x$ for all $x\geq 2657$. This is Corollary 1 in Schoenfeld: Sharper bounds for the Chebyshev functions $\theta(x)$ and $\psi(x)$. II, Math. Comp. 134 (1976), 337-360. Checking the finite range $2657>x\geq 2$ by a computer program, we find that the weaker inequality $|\pi(x)-\mathrm{li}(x)|<\sqrt{x}\log x$ holds for all $x\geq 2$. Conversely, if we assume this inequality for all $x\geq 2$, then the RH is true by Theorem 15.2 in Montgomery-Vaughan: Multiplicative number theory I.
