The generating function of the product of Legendre polynomials for the same $n$ is given by

\begin{aligned} \sum_{n=0}^{\infty} z^{n} \mathrm{P}_{n}(\cos \alpha) \mathrm{P}_{n}(\cos \beta)&=\frac{\mathrm{F}\left(\frac{1}{2} ,\frac{1}{2} ;1;\frac{4z\sin \alpha \sin \beta }{1-2z\cos (\alpha +\beta )+z^{2}}\right)}{\sqrt{1-2z\cos (\alpha +\beta )+z^{2}}} \\&=\frac{2K\left(\sqrt{\frac{4z\sin \alpha \sin \beta }{1-2z\cos (\alpha +\beta )+z^{2}}}\right)}{\pi \sqrt{1-2z\cos (\alpha +\beta )+z^{2}}} \end{aligned} where $P_n$ is a Legendre polynomial, $F$ is a hypergeometric function and $K$ is a complete elliptic integral of the first kind. https://www.researchgate.net/publication/269015726_A_generating_function_for_the_product_of_two_Legendre_polynomials

However, in the study of quantum physics, we need the similar result as above for following expression: \begin{align} \sum_{n=0}^{\infty} z^{n} \mathrm{P}_{n}(x) \mathrm{P}_{n-1}(x) \end{align}

Is there any result known? Any hints for this problem would be appreciated.
