An elite level figure skater who flat out refuses to do full run throughs IS lazy. Not just lazy, but ineffective at practicing in a way that would yield better results. Let's say you don't think I can call Carolina lazy because she practices 100 jumps a day...well, that just means she likes jumping, but doesn't like doing run-throughs. Someone who is lazy isn't necessarily someone who puts forth no effort, but rather someone who doesn't put forth any effort beyond what they "feel like" doing. I'm not saying she would definitely place better if she did do full run throughs, but I am saying that if she refuses to do full run throughs then she is jeopardizing the chance of placing better that she could have. There's honestly no reason other than nursing an injury or illness that would warrant an elite skater (and even non-elite skaters, to be perfectly honest) *not* to do full run throughs of programs.
