2. Drawing a wire with CTRL held down doesn't allow the wire to start and end off-grid. It's the same if I draw lines instead of wires. I can't find a 'Snap to grid' check box to untick.
After some thought, I think that you never could use the CTRL key, nor anything else, to make a wire not snap-to-grid.? I think wires and components can only snap-to-grid.

Reading the Help instructions:
The graphical annotations to the schematic; lines, rectangles, circles, and arcs; snap by default to the same grid as the used for electrical contacts of wires and pins. Hold down the control key while positioning these to defeat this snap.
This is the only place I found where it talks about not snapping-to-grid, and note that it applies ONLY to lines, rectangles, circles, and arcs.? It does not apply to Wires. ?Note the distinction between Wires and Lines.? Lines (right-click < Draw > Line) are non-functional, whereas Wires (F3, or the "Wire" toolbar button) make electrical connections. ?I think the conclusion is that holding down CTRL never worked for drawing wires off-grid.? For wires, CTRL only toggles whether they can be drawn at an angle.

It makes sense to me that Wires could never be made off-grid, because it could be challenging to connect anything to the off-grid end of a wire.? The schematic editor uses integers for location, and grid points are every 16 integer values - which means there are 15 chances to get it wrong and miss the end of a wire that is not on-grid.

You can hand-edit your .asc schematic file and move a wire's starting or ending points, making them off-grid.? It works.? Once in the schematic file, LTspice accepts it and leaves it off-grid when saved again.
