There is the Rayleigh dissipation function:
https://en.wikipedia.org/wiki/Rayleigh_dissipation_function
But when you switch from Lagrangian to Hamiltonian view point with dissipation, you get a Hamiltonian that is not time independent.
OK, that is also possible, but the advantage of using Lagrangian and Hamiltonian methods becomes less obvious in that case.
