Does Python CAMB perform interpolation of the CMB [math]C_{\ell}'s calculated at certain multipoles, to obtain the [math]C_{\ell}'s at each value [math]\in [\ell_{min},\ell_{max}]? Or does it compute the [math]C_\ell at each multipole [math]\ell? If it performs interpolation, is there a way to access the uninterpolated [math]C_\ell's?

They are interpolated by default. You can set CAMBparams.Accuracy.lSampleBoost = 50 to make it calculate all L without interpolation.
