The funds that are disbursed via the G.I. bill are earmarked funds specifically set out for use in obtaining post-secondary school education and as such are most typically unavailable for attachment by your spouse in regards to any amount of child support owed.
While there may be some exceptions to this depending on previous standing orders or agreements between the parties referencing a division of certain portions of these funds post disbursement, most often these funds are specifically paid directly to schools or institutions on direct payment schedule based upon costs associated therein. While it is possible to attach almost any funds post-disbursement to an individual, it is much more difficult to do so when those funds are disbursed to an institution and are specifically earmarked as such.
While I would still highly suggest that you contact an attorney to discuss the matter in more detail, based on the cursory view of the facts as stated I would say that the likelihood of your spouse garnishing or attaching those funds is somewhat remote.
