LND funding transaction stuck in mempool due to low fees
I solved the problem whit CPFP (children pay for parent).

I used the  unconfirmed change of the fund TX stuck in mempool to open a new channel.

At the time of broadcasting TX the median fee is around 150sat/vb, so i chose to slight increase at 200 sat to ensure good probability to push the first fund tx and the second one in the next block avaible.
