Column LLT polynomials are well-studied Schur positive symmetric functions defined by Lascoux, Leclerc and Thibon, and they have many nice combinatorial properties. We conjecture that column LLT polynomials are \(e\)-positive when substituting \(q\) with \(1+q\), and the coefficients of the \(e\)-basis expansion can be obtained by constructions of "inequality" posets.
