I would cut the flooring along the grout line nearest the wall and remove the flooring in that area. Make sure it's a razor sharp cut and as straight as possible. Replace it with a wood laminate type flooring. Pick a color to match the floor. It would look like it was wood framed from the tile to the wall. For the wall, the standard mop board molding would cover any deficiencies there, as it's usually around four to five and a half inches tall. And if you're really ambitious, do that wood floor 'trim' all around the room perimeter to appear as an intended 'frame' of sorts.
