We investigate the emergence of topological and correlated electronic phases in a twisted bilayer Kagome lattice constructed from carbonyl-triphenyl (CTP) supermolecules. Using symmetry-adapted moiré supercells and ab initio electronic structure calculations, we find that moiré modulation preserves the underlying Kagome node-localized wavefunctions while introducing momentum-selective interlayer hybridization. At a commensurate twist angle of $\theta =10.{83}^{\circ }$, a nontrivial topological index ${\mathbb{Z}}_2=1$ is found from the non-Abelian Wilson loop analysis across the combined subspace of the near Fermi flatbands (FFBs). In contrast, at a twist angle of $\theta =11.{46}^{\circ }$, while the net Chern number ($C$) of the full subspace remains zero, individual FFB acquires nonzero $C=\pm 1$ despite the absence of explicit spin polarization. This topological response arises from Berry curvature redistribution driven by moiré-induced inversion symmetry breaking. Both topological phases are accompanied by the van Hove singularities near the Fermi level, suggesting a favorable environment for interaction-driven instabilities. Our results establish twisted supermolecular Kagome bilayers as a chemically tunable platform for realizing frustration-enhanced topological states and potential correlated quantum phases in organic systems.
