I suggest below changes:

private addOperationToCommand(
    command: Command,
    drawingEntity: DrawingEntity,
  ) {
    const operation = new DrawingEntitySelectOperation(drawingEntity);
    command.addOperation(operation);
  }

  public selectCurrentDrawingEntities(drawingEntity: DrawingEntity) {
    const command = new Command();

    this.allEntities.forEach(([, drawingEntity]) => {
      if (drawingEntity.selected) {
        this.addOperationToCommand(command, drawingEntity);
      }
    });

    if (drawingEntity.selected) {
      drawingEntity.turnOffSelection();
    } else {
      drawingEntity.turnOnSelection();
    }
    this.addOperationToCommand(command, drawingEntity);

    return command;
  }

I believe that addOperationToCommand is not the best name for this method, because it actually adds concrete DrawingEntitySelectOperation.
However I would propose to not create this method at all. We can do like this in selectCurrentDrawingEntities method:

      command.addOperation(
         new DrawingEntitySelectOperation(drawingEntity)
      );

It looks like a bit overhead to create operations for already selected entities. Can we rework and rename this method to add only one drawing entity to selection?
