In recent years, layered kagome magnets have emerged as promising platforms for Berry curvature engineering and unconventional transport phenomena. Here, we present the single-crystal growth, magnetization, and electrical transport characterizations of the van der Waals-like layered antiferromagnet ${\mathrm{GdTi}}_3{\mathrm{Bi}}_4$. The system exhibits pronounced field induced first-order phase transitions. Comprehensive frequency, temperature, and field-dependent ac susceptibility measurements, and Hall analysis, reveals the formation of a spin-cluster-like glassy magnetic phase attributed to noncollinear spin textures. Additionally, the system demonstrates a colossal anomalous Hall conductivity $[{\sigma }_{xy}^A\approx 8.6\left(7\right)\times {10}^3{\mathrm{\Omega }}^{-1}\mathrm{c}{\mathrm{m}}^{-1}$ at 2 K]. Detailed scaling analyzes reveal the coexistence of skew scattering and intrinsic Berry curvature contributions to the anomalous Hall effect. First-principles calculations highlight flat-band near the Fermi level, with $f$ electrons of the Gd ion contributing large intrinsic Hall response. Thus, ${\mathrm{GdTi}}_3{\mathrm{Bi}}_4$ emerges as a rare layered kagome magnet, exhibiting Berry curvature induced giant anomalous and spin texture driven Hall responses, providing a versatile platform for exploring spin texture physics and advancing low-dimensional spintronic functionalities.
