However, if you insist on sticking to the mantra of not ending your sentence with a prepositioin, I think part of your problem here is that “Toys are meant to be played with" is passive. By adding the agent via a "by phrase" (e.g. by children) you could avoid "stranding" the preposition. Alternatively you could change it to "Children are meant to play with toys".
