Even the best lattice QCD calculations of mesonic properties at the physical pion mass are good to 1 part in 10^(4ish), nothing approaching the accuracy needed to detect new physics in the baryon sector. Calculations with baryons suffer from a severe signal-to-noise problem, and the latest calculation of a substantially-easier-to-compute quantity, the nucleon isovector axial coupling, is only at ~1% precision: https://arxiv.org/abs/1710.06523 (full disclosure: one author of said calculation).
