So, based on this question, a molecule containing a radioactive atom will break when the atom decays. But suppose you need a lot energy to break the compound apart — as in, more energy than the decay of the atom will release (obviously, a molecule this stable isn't actually possible… right?). Will the atom just be forced to stay static, or would something else happen?
I can't think of a way for the compound to break, since that would probably need free energy. But maybe the compound can "soak up" energy, so a sharp jolt or high heat can cause the atom to decay and the bonds to break?

While the arguments put forward in the other answers are in principle correct, it is important to note that nuclear decay processes span a huge parameter space, both in energy and half-life.
So to provide a counter example, let us look at the most special nuclear transition in this regard: Thorium 229, which has an isomeric state Thorium 229m, which can be obtained as a decay product of Uranium 233. The transition energy of this state is 8.28 +- 0.17 eV (source). Yes, eV! This transition is in the optical regime.
As a result, it gets affected by all kinds of electronic processes , for example, internal conversion . Also the chemical environment or rather the crystal structure is relevant (as stated here). Note that there is a huge body of literature on this subject and I only give examples here which are by no means representative of the whole work. For further reading see this and references therein.
Note that this is an extremely exotic transition, but also a very important one. Much effort is being invested into building an extremely precise nuclear clock using these nuclei.
So at least a weaker version of the question in the OP can be answered in the affirmative: there are radioactive decay processes that get strongly affected by the electronic environment.
Edit for clarity
I have been asked in the comments to clarify my answer with regards to how it addresses the question and what kind of nuclear transition we are talking about.
