Welcome!
1. If DYS or access to other resources is a consideration, then yes, you should think about obtaining a VECI, which would only have required two more verbal subtests. (Though since it's been nearly two years, you would have to wait out the full 24 months, and then retest with the whole WISC-V.) The raw scores you've listed for the VCI subtests aren't really the determining factor; those would be more relevant for the (eventual) Extended Norms. More importantly, DYS accepts a VECI score of 145+ as a qualifying score, but not a VCI.
2. It would be nice to have more interpretive information, but the value of asking for a more thorough write-up depends largely on the clinical skills of the evaluator. Also, whether you need a narrative report for access to a resource.
3. Which subtests were actually omitted? I see scores for all of the core subtests, plus a supplementary? Did the evaluator question the validity of the processing speed subtests? I should also mention that, given the diagnoses you listed, her "refusal" may actually have been a manifestation of one or more of her disabilities, in which case the scores may be more valid than at first appears. (For example, low PSI scores are often found in dysgraphia. Low WMI and/or PSI scores are often found in ADHD.)
If s/he truly refused because s/he found tasks "pointless" (rather than "pointless" being a mask for "I can't do this"), then there will be no particular advantage in going to another test (I also don't encourage retesting for its own sake--I would suggest having a specific reason for it, such as to elucidate a present educational or emotional/behavioral need, or to obtain access to resources). They all have tasks for which children see no obvious rationale. Sometimes I explain that they address different aspects of learning ability, some of which will be more natural for one person, and others for another person. Everyone has preferences; that is entirely normal. This is also only a small subset of the qualities and experiences that go into a person's development. It may be that your DC will be more cooperative with a little bit more preparative knowledge regarding the value and limits of value of cognitive assessment.
With regard to interpretive observations, the primary one is the obvious point that verbal abilities are very high. Fluid reasoning is also in the MG range. VS and WM are considered High Average (not the same classification as Average), and PSI is in the Low Average range. It is true that almost all the subtests that are not in VCI or FRI are Average. This is a profile that tends to be strong in abstraction, but not as strong in concrete skills, especially efficient work production.
On another note, I find the combination of Dx interesting, as I wonder if some of the behaviors ascribed to ODD might be related to the rigidity of ASD (e.g., is it defiance, or being anxious and "stuck"), and the impulsivity/poor self-regulation of ADHD.
