Hi I want to know how to create a bot
You'll have to create a client first to communicate moves between an engine and the lidraughts bot API. Or wait until sombody else had done this, see e.g. lidraughts.org/forum/general-draughts-discussion/lidraughts-bot-2
Is there no easy method? I can create bits in Lichess easily
For Lichess there are several bot clients that you can use out of the box, but nobody has made one for Lidraughts yet. If you can't make one yourself, you'll have to wait until somebody else does.
