mpmath.odefun does support complex points. You shouldn't use a general-purpose ODE solver, though. The holonomic ODE can be converted to a direct recurrence relation for the Taylor series coefficients, so you can analytically continue a solution very efficiently using Taylor polynomials of any order.
