Founding looked different for the Ymir Fritz, First King, Uri and Frieda (also it could be why Attack looks different now) and Ymir's Jaw looked nothing like Galliard's Jaw. The Fritz founding titan would obviously differ due to the span of generations between Ymir Fritz, the 145th king and eventually Uri.

And about Gaillard: It probably had to do about the fact that ymir was unable to harness jaw's true form but it is unclear why: it could be because marcel never transformed and thus jaws took ymir's pure form over, Or it could be because Ymir spent decades in her pure form.
