1. lock or hide all other shapes / layers. Pen Tool does not snap to locked shapes or points.
2. when the Pen Tool wants to snap to the current shape (line) which must be unlocked obviously, hold the SHIFT key. This will allow you to place a point right next to the line without snapping to it.
It will still snap to current shape's points, no fix that I'm aware of.
