All of the standard comprehensive cognitive assessments have some motor component to them. The NNAT, TONI, CTONI, and Leiter all have relatively minor motor demands, but are hardly comprehensive instruments (the name of the CTONI notwithstanding). I would say that selecting an instrument that has a lighter weight for timed motor tasks would be preferred.
The Stanford-Binet V, though beginning to show its age, does have few timed tasks on it (there is no processing speed composite), and no pencil/paper tasks.
The WJIV COG has no manipulative tasks in it, but does have timed pencil/paper subtests in the core; the WJ family also has a history of unusually low overall ability numbers in children who perform discrepantly low on the processing speed tasks. This latest revision does have an alternate composite score somewhat comparable to the Wechsler GAI, which does not include the cognitive efficiency clusters (working memory and processing speed, the latter of which is likely where fine motor deficits would impact). You might have to request that they include this version of the scoring in the analysis, though, as not every evaluator is accustomed to using this new cluster score. (Gf-Gc Composite, includes only Comprehension-Knowledge and Fluid Reasoning Clusters.)
The WISC-V includes both timing and manipulatives, even in the GAI (which does not include working memory and processing speed), but, among the GAI contributors, probably will result in possible low estimates only on Block Design, which is half of the visual spatial index, but the one included in the GAI and FSIQ. I think it provides a little more information on different aspects of reasoning than the WJIV Gf-Gc cluster.
The KABC-II also has one core subtest at this age that includes manipulatives (and another optional subtest that involves hand motions)--also half of the visual-spatial cluster. No fine motor speed cluster.
From a max number/access standpoint, it makes sense, of course, to select the instrument which is least affected by his relative weaknesses. From a clinical interpretation standpoint, however, it may well be more informative to administer an instrument which allows you to compare his motor-involved and motor-reduced performance, such as the WISC-V or KABC-II.
The WISC-V and WJIV are also modern instruments, with current norms, while the KABC-II is 12 years old, and the SBV is 13 years old.
