Recently, the KM3NeT Collaboration announced the detection of a 220 PeV neutrino from the celestial coordinates R.A. = 94$\mathop{.}\limits^{^\circ }$3 and decl. = -7$\mathop{.}\limits^{^\circ }$8 on 2023 February 13 at 01:16:47 UTC. The source for this extra-ordinary cosmic neutrino, designated KM3-230213A, is not identified yet but there has been speculation that it might be associated with a gamma-ray burst GRB 090401B. The purpose of this report is to search the association of this 220 PeV neutrino with potential GRB sources from a more general consideration of Lorentz invariance violation (LV) without predefined LV scale. We try to associate this extra-ordinary neutrino with potential GRBs within angular separation of 1°, 3° and 5° respectively and the results are listed in Table 1. We find the constraints E_LV ≤ 5.3 × 10¹⁸ GeV for subluminal LV violation and E_LV ≤ 5.6 × 10¹⁹ GeV for superluminal LV violation if KM3-230213A is a GRB neutrino.
