The Gauss-Bonnet invariant captures key aspects of the underlying geometry that has been shown to be an interesting way to form cosmological models beyond $Λ$CDM cosmology. In this work, we explore three competing cosmological models in $F(T,T_G)$ cosmology in the context of their evolution of the growth of structure in the Universe. This is a core test of the viability of any cosmological model. In our work, we show how these models are qualitatively competitive with $Λ$CDM cosmology for certain ranges of model parameters. Interestingly, the models can arrive at the same level of growth as $Λ$CDM while producing possible deviations at intermediate scales.</summary>\n    <category scheme='http://arxiv.org/schemas/atom' term='gr-qc'/>\n    <published>2026-03-02T14:05:05Z</published>\n    <arxiv:comment>14 pages, 3 figures</arxiv:comment>\n    <arxiv:primary_category term='gr-qc'/>\n    <author>\n      <name>Shivam Kumar Mishra</name>\n    </author>\n    <author>\n      <name>Jackson Levi Said</name>\n    </author>\n    <author>\n      <name>B.
