The static local-field factor (LFF) of the 2D electron fluid is calculated nonperturbatively using a mapping to a classical Coulomb fluid (Phys. Rev. Lett., 87 (2001) 206404). The LFF for the paramagnetic fluid differs markedly from perturbation theory where a peak near is expected. Our LFF has a quasi-linear small-k region leading to a peak close to , in agreement with available quantum Monte Carlo data. The structure in the LFF and its dependence on the density and temperature are interpreted as a signature of correlated scattering of electron pairs of opposite spin. The lack of structure at implies weakened Friedel oscillations, Kohn anomalies, etc.
