It is confusing to have a set of crimes, not all of which involve actual or even attempted killing, lumped together under a single term, and doubly so when that term implies killing.
are there any examples of accusations of the crime of genocide thus far that have not involved killing?
Article 3 defines the crimes that can be punished under the convention:
(b) Conspiracy to commit genocide;
(c) Direct and public incitement to commit genocide;
(d) Attempt to commit genocide;
(e) Complicity in genocide.
— Convention on the Prevention and Punishment of the Crime of Genocide, Article 3
while it might seem confusing, "Imposing measures intended to prevent births within the group" is a crime that can be punished under the convention if it is carried out in an attempt to commit genocide. same with deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part, or causing serious bodily or mental harm to members of the group. if the intent is to destroy the group or incite others to destroy the group, then it is included. killing people in such as way as to create plausible deniability, for example, to kill protestors at a distance week after week after week, especially young people, under the pretext of defense, when clearly they pose no clear and present danger, how many decades can you pull that off and still maintain plausible deniability. especially when some of your leaders are calling for all of them to be destroyed.
while it may seem confusing all of those circumstances are a means to an end if the intent is to destroy a group. especially when carried out in combination with eachother.
